What Happens if You Cut or Damage a Nerve in Your Finger?

Read Blog

Even the thought of cutting a nerve in your finger can send a chill up your spine. If you truly do cut the nerve itself, this really is as serious as it sounds, and you should seek care as soon as possible. The sooner you get help for a damaged nerve in your finger, the more likely it is that full functionality can be restored.

However, if the injury is not deep enough to sever the nerve, your hand can usually heal itself without surgery, although you still should seek emergency treatment when necessary.

What are nerves, really?

“This is getting on my nerves.”

“You really cut a nerve with that comment.”

“I’m nervous.”

Do these phrases and idioms really relate to what nerves really are and what they do? Well, yes, they do — in a sense — when you think of it in terms of nerves sending signals to your brain, which controls your emotions.

In simple terms, the body has two primary nervous systems: the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord. The peripheral nervous system is located outside of this area throughout the body.

Peripheral nerves transmit electric impulses into or away from the central nervous system as a form of communication. It’s essentially a communication network.

The peripheral nervous system consists of more than 100 billion nerve cells, or neurons. They run throughout the body like wires, connecting the brain to other parts of the body or various parts of the body with each other.

The peripheral nerves are made of bundles of nerve fibers, which are wrapped with layers of tissue that form what is known as the myelin sheath. The myelin sheath is responsible for speeding up nerve impulses, the intensity of which vary depending on their and the amount of tissue around them.

This drawing shows the three main nerves of the hand: the ulnar nerve, the median nerve, and the radial nerve.

How many nerves are in your hands?

Although there are a countless number of nerve cells, there are three primary nerve systems in your hands, wrists, and arms.

1. Ulnar nerve

The ulnar nerve is located at the pinky finger and the adjacent side of the ring finger. It provides sensations on the palm side of the hand. It travels up through the elbow and is responsible for the pain we feel when we bump our elbow.

2. Radial nerve

The radial nerve is responsible for sensations at the back of the hand at the little finger and the other half of the ring finger.

3. Median nerve

The median nerve starts at the shoulder and enters the hand through the carpal tunnel in the wrist. The median nerve is responsible for sensations in the thumb, index finger, middle finger, and part of the ring finger.

What happens if you cut or damage a nerve in your finger?

Many of us are familiar with the throbbing pain of a cut or injured finger. If you cut your finger and it is bleeding, the first step is to apply pressure to stop the bleeding. If the bleeding does not stop, you should go to your nearest hospital or urgent care facility, as you may need stitches.

If the sheath that covers the nerve remains intact after a cut, only the nerves farthest from the brain will be affected and die. (In other words, the deeper the cut, the closer it is to the nerve itself.) However, those can heal and grow back over time. Surgery is usually not necessary, but you will need to have the injury addressed by a medical professional for optimal healing.

If the injury is deep enough, you should seek emergency care as soon as possible, which may entail surgery to reattach the severed ends of the nerve sheath to one another.

In some cases, the cut may be deep enough that it damages the nerve itself. If that happens, the gap between the two parts of the nerve will have to be repaired, usually through a nerve graft from another part of the body. Another possibility is using a synthetic nerve conduit to bridge the gap in the nerve.

If the nerve in your finger was damaged due to a crushing injury, you may have to wait for the initial crush trauma to heal before the nerve damage can be addressed.

If you have damaged or cut a nerve in your finger, it’s important to seek care as soon as possible. If the need for treatment is urgent, go to your nearest emergency room. Otherwise, contact one of our hand surgery offices, located in West Bloomfield, Warren, Howell, and Macomb, for treatment as soon as possible.

Common Causes of Stiff Hands

Read Blog

Stiff hands can hit you all of a sudden. One minute you’re going about your day and the next, you’re wiggling your wrists in hopes of bringing life back into your fingers.

Certain serious medical conditions can definitely bring this on, but in other cases, your hands may feel stiff for no apparent reason.

Well, there most likely is a reason why your hands are stiff, and self-care may be your first line of treatment and prevention.

5 Common Causes of Stiff Hands

Stiffness in your fingers, thumb, and palm occur when there is a problem in a joint, including the ligaments and muscles.

One of the greatest culprits is arthritis, which isn’t a condition as much of a description of more than 100 types of ailments. Types of arthritis that may lead to stiff hands include:

Other medical conditions that can contribute to the sensation include:

Environmental factors and how you use your hands may lead to stiffness as well, such as gaming for too long or spending too much time outside in freezing temperatures.

Questions and Answers

Whether your hands become stiff temporarily for a few minutes or it’s an ongoing symptom, the reasons why this happens can be mysterious. When you see Dr. Arora, tell him about your symptoms in detail, and he will help identify the source of your problems.

In the meantime, here are some of the common questions we hear about hand and joint stiffness along with the basic answers.

Why do my hands get stiff in the morning?

One of the simplest answers is that you slept on them or leaned on them too much as you were sleeping. Avoid leaning on your wrists or tucking your hands under your head as you sleep. Using a brace at night may help you keep your wrists straight.

Otherwise, a common cause of stiff hands in the morning is worn joints or muscle tightness. This may be an indicator of arthritis, but not necessarily. Over the course of your life, your joints experience a lot of wear-and-tear; specifically, the cartilage in your joints dries out, stiffens, and loses lubrication.

This can lead to weaker muscles and stiff tendons, which may tighten even more as you sleep because you’re not moving. Lack of movement allows fluid to build up, which can stiffen tissues. When we move, bodily fluids move through the body more evenly, which can increase flexibility.

Simple lifestyle changes may help combat stiffness in your hands in the morning, including using proper mattresses and pillows, avoiding cold temperatures, staying hydrated, and maintaining a healthy diet. You also should get regular exercise that is ideal for your body’s needs, so talk with Dr. Arora about stretches and exercises you can do to strengthen the muscles in your hands.

Why are the symptoms bad at night?

Just like our eyes and legs, our hands get a lot of use during the day. For that reason, you may feel more stiffness, pain, or throbbing in your hands in the evenings. Resting your hands will help them recover from the everyday grind. That’s the simple answer.

Otherwise, if your hands get stiff while you sleep, it could be a sign of a more serious condition, so talk with Dr. Arora about your symptoms.

Why does cold weather make my fingers stiff?

Momentarily, that’s actually a good sign; it means your body is working as it should. Our fingers and toes are designed to protect the rest of our bodies. In the cold, our blood vessels constrict to keep the core of our bodies and our vital organs warm. That may leave our fingers and toes colder and stiffer.

If you keep that up too long, though, you may experience frostbite in your extremities, which can be very dangerous. Help your body stay warm in the cold by wearing gloves, thick socks, and boots, as well as hats that can cover your ears. If they become wet, change into dry clothing as soon as possible. If you are outside shoveling or playing in the snow, go indoors every 15 minutes or so to warm up.

How do you treat stiff hands?

Treatment for stiff hands will depend on its causes, but some home remedies may help.

  1. Ask our hand therapist, Lodia, about hand exercises that can help you stimulate your blood flow in the morning or relieve overuse symptoms in the evening.
  2. Over-the-counter anti-inflammatory medications may help relieve swelling that is causing stiffness in your hands. Talk with Dr. Arora to determine if this will help you. He may have specific medications that would be preferable in your case.
  3. You can use a brace while you sleep, while participating in hobbies, or at work if your job requires intense use of your hands.
  4. Gently stretch your hand muscles to loosen them. Ask Dr. Arora or Lodia about how to loosen up your hand muscles safely.
  5. Take a lukewarm shower or bath to relieve stiff joints. Avoid water that is too hot, as this can dry your skin, which could make your hands feel tighter.
  6. Use a warm compress or heating pad for only several minutes to relieve stiffness. Be sure to wrap the heating device in a towel before placing it on your skin to avoid burns or swelling.

Diagnosis and Treatment

The first step is to determine why you are experiencing stiff hands. Once the cause is identified, we can advise you on the best course of action, whether it’s simple self-care, hand therapy, medication, or the use of support devices. Surgery may be required in some more serious cases when other remedies do not help.

If your stiff hands are regularly causing you discomfort or you are concerned that this may be due to a serious medical condition, call us to schedule an appointment with Dr. Arora. We will help you identify the cause of your hand symptoms and devise a treatment plan that works for you.

What is the Difference Between Osteoarthritis and Rheumatoid Arthritis?

Read Blog

The differences between osteoarthritis and rheumatoid arthritis are significant, but the ability to identify one over the other can be somewhat elusive to the general public. A proper diagnosis is crucial for effective arthritis treatment.

The symptoms of these two common forms of arthritis may be similar, but the conditions are actually very different.

The word “arthritis” itself isn’t as much of a diagnosis as a description of more than 100 different types of ailments that involve joint pain or inflammation. Osteoarthritis and rheumatoid arthritis are two of the most common forms. According to the Centers for Disease Control, more than 32.5 million U.S. adults suffer from osteoarthritis. Rheumatoid arthritis affects more than 1.3 million adults in the U.S.

To help you communicate your concerns to Dr. Arora, we offer the following comparison as a guide.

What is Osteoarthritis?

In very general terms, osteoarthritis occurs when cartilage in a joint wears out. It usually begins in one joint and may never affect other joints.

The pain can be mild, moderate, or severe. Moderate or severe osteoarthritis pain can make it difficult for patients to complete everyday activities, such as buttoning a shirt or tying their shoes.

It is most common among women and occurs more frequently as people get older. Other risk factors for osteoarthritis include obesity, genetics, and joint injury or overuse.

What is Rheumatoid Arthritis?

Rheumatoid arthritis is an autoimmune disease. When this occurs, the immune system essentially “malfunctions” and attacks the synovial membrane that encases and protects the joints. It frequently affect several joints at the same time.

Beyond the pain, inflammation, and swelling common in other forms of arthritis, rheumatoid arthritis symptoms may include fever, anemia, fatigue, and loss of appetite. Rheumatoid arthritis may also show signs in the skin, eyes, lungs, heart, kidneys, salivary glands, nerve tissue, bone marrow, and blood vessels. It tends to be symmetrical, so symptoms may occur on both sides of the body simultaneously.

This form of arthritis is a chronic condition. There is no cure, and it is likely to progress over time. However, treatment options can reduce pain, make the symptoms manageable, and prevent significant joint damage.

Women are more likely to develop RA than men are. RA can begin at any age but most commonly starts in middle age. Other risk factors for rheumatoid arthritis include family history, smoking, and excess weight.

4 Key Differences Between Osteoarthritis and Rheumatoid Arthritis

1. Number of Joints Affected

Osteoarthritis may only affect one joint. Rheumatoid arthritis may affect several at the same time.

2. Symmetry

Rheumatoid arthritis tends to be symmetrical, meaning it affects both elbows, for instance. Osteoarthritis is more centralized, so it might or might not affect both sides of the body.

However, both sides of the body may become affected due to the exertion of too much pressure on one side. For example, if you experience osteoarthritis pain in your left wrist, you may use your right wrist more often, eventually causing the right wrist to act up as well.

3. Duration of Symptoms

The duration and extent of the pain is different.

With RA, joint pain and swelling can come and go, but the disease never really goes away. The goal of rheumatoid arthritis treatment is to make you feel better and get your symptoms under control, known as “remission.”

Osteoarthritis is also permanent and the pain and swelling are similar, but the condition can improve over time.

4. Additional Symptoms

Rheumatoid arthritis may have symptoms such as fever, fatigue, anemia, and loss of appetite. Osteoarthritis is usually only pain, swelling, and some loss of flexibility in the particular joint that is affected at the time.

If you are experiencing arthritis pain in your hands, wrists, or elbows, it’s important to determine the type of arthritis in order to create the best treatment and prevention plan for you. For an evaluation, diagnosis, and arthritis treatment, make an appointment to see Dr. Arora in Warren, West Bloomfield, Howell, or Macomb Township.

How to Find the Right Hand Surgeon in Howell for You

Read Blog

If you are looking for a hand surgeon in Howell, you may feel somewhat overwhelmed.

Where do I begin? Should I look for a hand specialist, or will a general practitioner be better? Do all hand doctors offer the same services? Is my condition even about my hands, or is it something else?

Finding a Hand Surgeon in Howell

Answering these questions is the key to finding the right local hand specialist for you. Although each patient and every case is different, following are several tips to help you find the best hand doctor to diagnose and treat your particular condition.

Do I need a hand specialist, or would a general doctor be able to help?

You can certainly go to your general practitioner to discuss your conditions. However, if your symptoms truly stem from your hands, wrists, elbows, or elsewhere in your arm, you may be referred to a hand specialist. A hand specialist will then be able to:

Are all hand doctors the same?

Hand doctors may provide similar services, but it’s important to look for a hand surgeon in the Howell area with many years of experience. An experienced specialist will likely offer more comprehensive services and be able to more easily identify sources of your problems in order to diagnose your condition. Experience is also the key for efficiency, better results, and optimal recovery.

How do I find the right hand surgeon near me?

Do your research not only online, but by using good, old-fashioned word-of-mouth. Talk to people you know who have been treated by a hand doctor to see if they would recommend that doctor. When you do have these discussions, remember to ask your friend or family member the following:

  • How efficient were the services? Were they able to see you quickly?
  • Was the office staff welcoming and attentive?
  • Did the doctor greet you with professionalism?
  • Did the doctor take the time to answer all of your questions?
  • Did you feel like the doctor truly cared about you as a person?
  • Do they have modern equipment and technology, and do they seem to keep up to date with modern trends in the industry to ensure their patients get the best services?
  • Was there a hand therapist on staff?
  • How do you feel now? Did you recover?
  • Did you have surgery? Can you tell me about what happened before and after the surgery?
  • Have you had follow-up appointments? Do you visit them regularly? Do you find these appointments beneficial?

In addition to speaking with people who may have visited a hand doctor recently, take some time to do your research online. Review doctors’ websites and read the online reviews.

Reviews can be a very powerful tool, but as you are reviewing them, remember this basic fact about statistics: The more reviews there are, the more accurate they’re likely to be. Don’t let one or two negative reviews sway you when there are dozens of very positive reviews. On the other hand, if you do see a trend of too many similar negative reviews, that may warrant further scrutiny. Finally, gauge what really matters to you as you read the reviews.

Can the doctor treat my specific condition?

Clearly, that’s going to be the most important factor in finding the best hand surgeon in Howell for you. Review the websites or call the offices to find out if they can treat your particular condition.

Is the doctor’s office nearby?

Although it’s not always the most important aspect, convenience is definitely important too, especially if you are undergoing surgery and need someone else to drive you to and from the doctor’s office.

Get to Know Arora Hand Surgery

Once you analyze all of the above factors, we have no doubt that Arora Hand Surgery will be at the top of your list. Dr. Avery Arora, Physician Assistant Ashley, and Occupational Certified Hand Therapist Lodia work together as a comprehensive team to restore and enhance patients’ hand functionality and overall quality of life.

Looking for a West Bloomfield Hand Specialist? Why Experience Makes the Difference

Read Blog

Are you betting that all hand specialists in the West Bloomfield, Michigan area are the same? We’ll take that bet!

Truly, we can see why you might think that. Typically, people who experience a hand injury go to the first local hand specialist they can find. If you need care for an injury, that makes sense. On the other hand, if you’re looking for effective recovery and long-term treatment, you need to find a local hand doctor who has many years of experience in treating traumatic injuries as well as various other hand conditions.

Why is experience so important when you’re looking for a hand specialist? Let us point out a handful of reasons experience makes the difference.

1. The doctor may have a greater wealth of knowledge regarding various hand conditions.

As you are looking for a hand doctor, it’s important to find one who can diagnose and treat a wide variety of hand conditions. In fact, that’s why it’s ideal to go to a specialist specifically rather than a general doctor. The hand is an intricate, complex system, and any number of issues can cause similar symptoms. An experienced doctor will be more skilled at identifying the exact source of the pain and the condition that’s causing it.

2. The recovery process and results are more optimal.

Our hand surgery team learns something new every day, and the longer we work, the more we learn. It’s as simple as that. We’ve come across stumbling blocks, unexpected excellent outcomes, tremendous successes, and even a few failures, and we’ve learned from them all. Experience leads to knowledge about what to do, what not to do, and how to do it. And nothing can replace “time” in order to gain that expertise.

3. An experienced hand specialist in West Bloomfield may provide more accurate diagnoses.

If a hand doctor has earned his or her title, he or she is likely very familiar with all the various hand conditions a person may experience. There are many great hand specialists in Michigan, it’s true. However, reading about it is much different than seeing it in person or hearing what the patient has to say.

An experienced hand specialist would dig deeper and look beyond the obvious to pinpoint conditions that may mask themselves as something else.

4. The fluctuating Michigan weather may have an effect.

Cold weather can cause conditions such as hand arthritis and Raynaud’s disease to flare up. A local hand specialist who has years of experience in treating patients in Michigan specifically may have a few more helpful tips that can relieve weather-related flareups.

It’s also not all about the winters. Dramatic changes in weather conditions can lead to hand pain, numbness, and tingling as well. If you’re looking for a hand specialist, it’s important to find one who understands what all four seasons in Michigan can do to your body — and maybe even your mind. It all goes together, after all.

5. You gain peace of mind with proper treatment.

When you choose the best hand specialist in the West Bloomfield area, you can have greater confidence in the diagnosis, treatments, and guidance. Skilled hand doctors have most likely successfully treated countless of patients who have your condition, so they are more familiar with its intricacies.

You can also feel free to ask as many questions as necessary and know that you’re getting the thorough answers you deserve.

If the condition is treated properly the first time, you are less likely to have to return to get it treated again, with the exception of basic follow-up appointments. A condition that is improperly diagnosed or treated will likely not go away on its own. You might get temporary relief, but eventually you will have to return for more permanent solutions.

As you are looking for a West Bloomfield hand specialist, you will find that Dr. Arora has the depth of knowledge, expertise, and experience you need for more effective recovery. Contact us to make an appointment to see Dr. Arora at his office on Orchard Lake Road.

How Do Nails Grow Back?

Read Blog

You clip them one day. They’re back two days later.

You chip one one day. It’s back to normal within a day.

You hit one with a hammer, and the bruise goes away within a few weeks.

You overdo your manicures to the point that the nails become thinner, and they’re back to normal within a month.

You paint them one day … ok, well, that one doesn’t make the nail shorter or thinner, but it’s still one of the many things your nails go through in your lifetime — and yet they’re among the most resilient parts of our bodies.

How in the world? How does it happen? How do nails grow back so easily and look relatively the same? Is there a secret magic chamber hiding in our third knuckles? … And why, oh why, can’t our teeth do the same thing?

How Do Nails Grow Back?

How nails grow back is essentially about science.

Nails start out as living cells, which is why they continue to grow, but they harden and die once they become the nails that we see. That’s why it doesn’t hurt when we clip or file them.

Nails are made of a substance called keratin, which is the same thing that our hair is made of. And that makes sense. Both continue to grow throughout our lives, barring a significant injury or medical conditions.

The cuticles on our fingers and toes serve to protect the roots of the nails, which sit behind the cuticles. The root, or matrix, is a pocket of flesh that is connected to blood vessels that supply the nail with nutrients it needs to make new cells.

Fun fact: A fetus starts to grow nails when it is only 20 weeks old, and the baby’s tiny toes and little fingers have full nails by the time it’s born.

So, no, unless you’re Penn or Teller, there’s no magic in your hands — but the resiliency of our nails is still fascinating.

Can You Completely Lose a Fingernail?

Nails almost always grow back, and that’s the case even after accidentally whacking one with a hammer. It might look a little different, but typically you will get it back.

The reason for that is because it would actually be challenging to get under the root of the nail to the matrix in a manner that damages it for life. It’s a tough little pocket.

Only in very rare circumstances is the entire matrix damaged for good, and if that happens, the nail won’t grow back.

To answer your question about teeth — teeth are not made of keratin, and they’re not even “bone,” contrary to popular belief. They’re made up of enamel, dentin, cementum, and pulp.

So, no, as we humans are today, we can’t grow our teeth back … yet. It’s a nice little dream, though, isn’t it?

Clubbed Thumb Surgery: Is it Possible?

Read Blog

In many ways, clubbed thumbs or toe thumbs are endearing. They’re short, cute, and would certainly stand out if you’re trying to hitch a ride, so you can leave all those “plain-thumbed” hitchhikers in the dust.

Even though there’s medically nothing wrong with having stubbed thumbs, some of their owners often feel somewhat self-conscious about them.

Truly, there’s no need to feel that way. In fact, Dr. Arora would not advise or perform any type of surgery for clubbed thumbs in 99.99% of the cases he has seen.

However, if you are having trouble gripping or writing or have associated hand conditions, surgery for clubbed thumbs may be possible albeit risky.

Facts About Clubbed Thumb Surgery

Before we get into the basic facts about clubbed thumb surgery, let’s define what a clubbed thumb is.

Also known as a “toe thumb” or “stub thumb,” a clubbed thumb is more formally identified as a Brachydactyly type D skeletal variation. It may also be called “Brachymegalodactylism” . . . such a big word for such a little thumb, right?

Speaking of “little,” a clubbed thumb is simply about 2/3 the size of a longer thumb. The nail bed may be shorter and wider as well. Stub thumbs are genetic, just like the color of someone’s eyes or hair.

There is no simple surgical solution for clubbed thumbs. Risks include scarring, loss of sensation, and abnormal nail growth.

Surgery options for this type of brachydactyly are not formalized in any way in the United States. Some treatments may be completed in other countries, but they are not typical for the U.S.

The primary type of surgery for clubbed thumbs is an osteotomy. During an osteotomy, the bone is cut, and a bone grafting material is used to reshape the thumb, making it longer and narrower as needed.

However, your hand is a complex system. If you were born with clubbed thumbs, they most likely function optimally with the rest of your hand, just like a well-oiled machine. Narrowing the thumb or making it longer may change the dynamics of your hand’s functionality.

Dr. Arora’s philosophy is generally, “If it ain’t broke, don’t fix it.”

Because clubbed thumb surgery is typically not advisable, just keep this in mind. Up to 3 percent of people in any given population have stub thumbs, so you’re not alone. In fact, some very beautiful and famous celebrities have toe thumbs.

If nothing else, consider it a gift — a beautiful feature that highlights how unique you really are.

Hand Muscle Anatomy: How Many Muscles are in the Hand?

Read Blog

Have you ever really stopped to think about how spectacular your hands are? You use them for just about everything in life — from pumping iron at the gym to pumping gas at the gas station. They can be flat, or they can be clenched into fists. You can wiggle your fingers all around, bend them, and use them to point at someone. Our hands are truly a thing of beauty; there aren’t many other areas of our bodies that can take so many different forms. Just how many muscles are in the hand to enable all this power?

The hand muscle anatomy is very intricate, understandably, and most of the hand movements are actually controlled by the forearms.

How Many Muscles are in the Hand?

There are about 30 hand muscles, most of which lead to the wrists and forearms.

The formal terms for the various types of hand muscles are:

  • Dorsal interossei and palmar interossei muscles
  • Lumbrical muscles
  • Hypothenar muscles, which include abductor, flexor, and opponens digiti minimi
  • Thenar muscles, which include abductor pollicis brevis, flexor pollicis brevis, and opponens pollicis muscles

Technically, there are no muscles in the fingers, with the exceptions of the adductor pollicis and abductor pollicis longus at the base of the thumb.

How many muscles are in the hand? About 30 muscles are in the human hand, including lumbrical muscles as shown in this graphic.
Lumbrical muscles

If that all sounds rather foreign to you, don’t worry. We’ll explain.

1. The interosseous muscles are a network of muscles found on and in between the knuckles that enable us to bend the joints in the fingers. The dorsal muscles are used to spread the fingers, while the palmar muscles are used to bend them.

There are four dorsal interosseous muscles in each hand.

Palmar interossei consist of four muscles each that attach to the first, second, fourth, and fifth fingers. The third finger does not have a palmar interosseous muscle.

2. The lumbrical hand muscles extend to underneath each finger. We use them to straighten our fingers and bend the joints. There are four in each hand.

3. The three muscles on the side of each of your hands near the small finger are the hypothenar muscles. They enable you to move the pinky away from the ring finger, bend the pinky, and make a fist.

4. The thenar muscles are perhaps the most recognizable. They are three short muscles in the thick area of your palm under your thumb. These muscles give the thumb the ability to move the way it does, as well as enable us to grasp items.  (If you’re interested in an additional nugget of medical trivia, the bulge under your thumb is known as hypothenar eminence.)

5. The two muscles near the thumb, the adductor pollicis and abductor pollicis longus, enable us to pinch. One is located between the index finger and thumb, and the other passes through the wrist.

Possible Causes of Hand Muscle Pain

If you are reviewing the anatomy of the hand because you are feeling pain in your hand muscles, you may wish to learn about the most common causes of this pain. They include inflammation, nerve damage, basic overuse, and sprains, fractures, or other traumatic injuries.

Chronic health conditions also can lead to hand pain. They include:

If you have pain in your hand, see our hand specialist at our Warren, West Bloomfield, Macomb Township, or Howell office. Dr. Arora can analyze the skin, joints, and muscles of the hand and recommend tests to identify the source.

Dr. Aroras office from my first call to schedule my appointment was friendly. Walking in the first day, I felt like I was in a nice atmosphere. Dr. Arora was EXCELLENT in taking great care of my hand injury. He was gentle and very understanding to the concerns I had about my hand. His expertise was admirable and I would recommend anyone with an injury to their hand to his office to be under his care. Because of him, I have healed faster than expected and will make an 100% recovery! Thank you Dr.

Jackie S.

I first thought I was going to have to have painful injections or surgery, but Dr. Arora suggested physical therapy may do the trick. I was doubtful, but I agreed to do it. Now, my pain is gone, and with the help of an ergonomic keyboard at work to keep my hands in the correct position, I am virtually pain free. The therapy strengthened my wrists and shoulders, and built more flexibility into my wrists.

Jerry T.

My experience with this doctor was positive from the outset. Dr. Arora was kind and spent a great deal of time with me. Staff was friendly. The office was nice and bright.
