How do you diagnose a nerve injury?

In order to fully determine the extent of the damage to the nerve, the doctor may order an electrical conduction test to determine the passage of electrical currents through the nerves. Two of these tests are electromyography and nerve conduction velocity.
Diagnosis of Peripheral Nerve Injury
  1. CT scan.
  2. MRI.
  3. MRI neurograph.

Is nerve damage hard to diagnose?

Nerve conditions can be hard to diagnose, and many patients live for years without an explanation or effective treatment for their muscle weakness or pain. Our specialists understand that the cause of a nerve condition is not always obvious and often requires a bit of detective work to uncover.

Can nerve damage fix itself?

When one of your nerves is cut or damaged, it will try to repair itself. The nerve fibres (axons) shrink back and 'rest' for about a month; then they begin to grow again. Axons will regenerate about 1mm per day. The extent to which your nerve will recover is variable, and it will always be incomplete.
