How do you treat nerve damage in the hand?

If I injure the nerves of my hand, what kind of treatments can I expect? Nonsurgical treatment of nerve injuries can include rest, splinting, icing, and physical therapy. If the nerve has been severed, then surgery will be necessary to rejoin the disconnected ends and restore function and feeling.

Can a damaged nerve repair 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.

What test shows nerve damage?

A nerve conduction velocity (NCV) test — also called a nerve conduction study (NCS) — measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin.

Can nerves heal on their own?

They can repair themselves if the injury is not too severe. Damage to nerves can be severe. Because of their structure and function, nerves do not heal as quickly as some body parts do, but sometimes nerve damage can heal on its own.
