Welcome to NT!

Nerve pain is awful. However, as Mrs. D said, in some cases nerves can regrow. The rate of regrowth is very slow - about 1mm a day. The standard thought is that after two years you've got back as much as you're getting.

Sometimes it can be very painful when the nerve "wakes up." (My PT is always delighted when I come in complaining about a new shooting pain somewhere.) If there hasn't been a signal for a long time it takes a while to get everything back to normal. I suffered extensive nerve damage in a car accident and discovered that even after the nerve grows back, it can take time to reestablish the proper connection with the brain. For example, for eighteen months I had no feeling in my hands. I've regained a bit, but it has taken extensive therapy to remind my brain what hot and cold are.

Nerve injuries require patience, which is in short supply when one is in pain. We're all here to help you through it.
