Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings. The MRI scan images are obtained with a magnetic field and radio waves. No harmful ionizing radiation is used.

What kind of doctor would I see for nerve damage?

Neurologists are specialists who treat diseases of the brain and spinal cord, peripheral nerves and muscles. Neurological conditions include epilepsy, stroke, multiple sclerosis (MS) and Parkinson's disease. Dr.

Can finger nerve damage be repaired?

Surgical nerve repair can restore sensation and movement to the hand and fingers and must be done promptly to minimize long-term damage. An orthopedic surgeon will typically try to complete a direct nerve repair if possible. Direct nerve repair reattaches the damaged nerve endings to one another.

Can finger nerves repair themselves?

The sooner you get help for a damaged nerve in your finger, the more likely it is that full functionality can be restored.

Hand or wrist nerve injury complications

In some cases, if the nerve is completely severed, it can result in permanent loss of sensation or feeling. Complete recovery may not be possible for some nerve injuries.

How does a neurologist check for nerve damage?

By measuring the electrical activity they are able to determine if there is nerve damage, the extent of the damage and potentially the cause of the damage. Frequently the neurologist will recommend common, noninvasive neurological evaluations such as electromyography (EMG) and nerve conduction velocity (NCV) testing.

What is an EMG test?

Electromyography (EMG) measures muscle response or electrical activity in response to a nerve's stimulation of the muscle. The test is used to help detect neuromuscular abnormalities. During the test, one or more small needles (also called electrodes) are inserted through the skin into the muscle.

What causes nerve damage in hands?

Nerves can be damaged by too much pressure, by stretching, or by a cut. Carpal tunnel syndrome is an example of a problem that arises from too much pressure on the median nerve in the hand.

Does CT scan show nerve compression?

A CT scan can show a large herniated disc or spinal stenosis. It doesn't show nerves.

Why would a doctor order a nerve conduction test?

Nerve conduction studies are done to: Find and evaluate damage to all the nerves that lead away from the brain and spinal cord to the smaller nerves that branch out from them. Help diagnose nerve disorders, such as carpal tunnel syndrome or Guillain-Barré syndrome.
