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.

Finger Nerve Damage Treatment and Diagnosis

Read Blog

Your fingers are invaluable to your ability to function each day. They perform critical tasks like tying your shoes, grasping doorknobs, handling eating utensils, and dozens of other things that you might take for granted. When you suffer nerve damage in your fingers, you quickly realize how important they are to your everyday life. You can regain your function and continue your daily routine without issues by learning what finger nerve damage is and how you can treat yours at Arora Hand Surgery.

As its name implies, finger nerve damage is damage to the nerves in your fingers. This condition can be caused by any number of factors like:

  • Injuries
  • Repetitive stress
  • Diseases like diabetes
  • Poor circulation

Finger nerve damage can affect people of any age, but it especially targets adults who suffer from illnesses like diabetes or work jobs that require them to perform repetitive tasks. However, it is one of the easier nerve conditions to diagnose and treat as long as it is addressed early before it results in permanent damage to the fingers.


We may use a series of tests to determine if patients suffer from nerve damage in the fingers. We may diagnose you with this condition if you suffer from symptoms like:

  • Pain anywhere in your fingers
  • Tingling
  • Numbness
  • Burning
  • Visible deformities like drooping
  • Limited motion
  • Inability to use fingers properly or at all
  • Underlying disease like diabetes or poor blood circulation

If you have any of these symptoms, you may be diagnosed and treated for finger nerve damage.

Finger Nerve Damage Treatment

Nerve damage in the fingers responds well to a variety of treatment options. Depending on the severity and cause of your nerve damage, you may be advised to undergo a number of treatments. It is recommended that you follow the advice of our doctor if you want long-lasting or permanent relief from your finger nerve damage.

You can learn more about your treatment options for finger nerve damage during a consultation with Dr. Arora and his team at Arora Hand Surgery. We have offices in West Bloomfield, Howell, Warren, and Macomb. Contact us today to schedule an appointment and get started.

Symptoms of Finger Nerve Damage

Your hand is a marvel of design. The human hand has a level of flexibility and dexterity that no other tool on the planet can match. Even though scientists and researchers are trying to mimic the functions and movements of the hands, the artificial alternatives that they create fall far short from the reality. What makes your hands such a powerful tool is the series of nerves that you have in your hands, as well as nerves located in other parts of your body that are designed to control and provide strength to your hands. As such, if you are experiencing finger nerve damage, you will likely exhibit a number of uncomfortable symptoms.

An example of a nerve in the finger is the radial nerve. This is a nerve that goes under your arm, controlling your triceps muscle. This nerve is also responsible for the twisting moments in your wrist and your fingers. It is what gives parts of your hands their ability to feel things and to have different sensations.

If you injure the radial nerve, you may be left with what is known as radial neuropathy. There are a lot of ways that you could damage this nerve. These include physical trauma, exposure to toxins, or infection. Often times, you will know that you have this form of nerve damage because your hands and your fingers feel numb. They may feel like they are burning, or they may feel like they are tingling. Another indication that you are dealing with this form of finger nerve damage is a weakness in your fingers. You may not be able to move your fingers like you used to, or it may be difficult to twist your fingers. If the nerve damage is addressed, you will see the strength in your fingers return.

There are a whole host of ways that you can damage the radial nerve. They include breaking the bones in your upper arm, sleeping with your arm in a weird or awkward position, pressure put on the back of your arm because you’re sitting in a chair in an awkward position, damage caused by using crutches for an extended period of time, hurting your arm by falling, or having your wrist in a constricted position for an extended period of time.

It is possible to develop finger nerve damage by doing repetitive movements. These can include movements that require you to grasp something while swinging another thing back and forth. There are other conditions that can affect your entire body that might damage your nerves. For example, kidney disease, diabetes, and some forms of inflammation can damage the radial nerve, which can then affect the strength in your fingers.

It’s important to remember that your fingers do not have any muscles in them for movement. All of your finger’s ability to move and their strength comes from your forearm and triceps. When the nerve that controls these muscles is damaged, the effect is felt in your fingers.

If you are experiencing symptoms of finger nerve damage, make an appointment at Arora Hand Surgery as soon as possible. Contact us today at our office in Warren, Macomb, West Bloomfield, or Howell to schedule a consultation and learn about your treatment options.

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.

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.
