I don't think anyone can tell you whether the nerves will heal or not, but they might. The body has amazing healing abilities, beyond what most doctors have been taught. Eat a healthy diet with plenty of whole vegetables and fruits. Avoid sugar, processed carbs, and processed foods in general. And get some exercise.

As I posted 10-29-13:

See the podcasts here, several regarding supplements:

I think the one on magnesium and the one on alpha-lipoic acid and acetyl-l-carnitine are very important.

Also there is an image here titled Nutrients for Neuropathy that I copied from a book I had (let me know if you can't get to these):
