As always, this answer does not constitute medical advice. I would advise talking to your Primary Care doctor or Neurologist.

Nerve damage is a complex topic. While it can't be cured with medications, often with aggressive physical and occupational therapy--as well as treatments by peripheral nerve specialists--it can be improved and can heal in time, although some people don't get back to their pre-injury baseline.

Depending on the cause, and if surgery is not needed , many types of nerve damage can recover on its own. Physical therapy may help, but no medication will make any difference. Leon Rosenberg

It depends on the degree or extent of the damage and duration. The more extensive the damage and the longer the time since the damage, the less likely  for a cure. The less extent and the less time the better the chance for a full or near complete recovery with the appropriate therapeutic intervention  Good luck. Dr. F Sent from AOL on Android
