--don't have a lot of options for nerve healing; they tend to attempt symptomatic relief (which is where all the anti-epileptic and anti-depressant drugs come in).

Some more enlightened ones may be aware of nutritional supplements (many of which we talk about) that may help the nerves heal themselves, but this also would involve halting, or at least slowing down, whatever is damaging the nerves in the first place. People with compressed nerves can do physical therapy, or as a last resort, surgery, to relieve the pressure on the nerves and allow them to recover. People with diabetic neuropathy can get their blood sugars under tight control. People with documented autoimmune neuropathy can try immune modulating treatments to slow down/halt the immune attack on the nerve, and so on. (This is why finding a cause may be important for many people, though many neuropathies remain stubbornly "idiopathic".)
