What are the best treatments for Wartenberg's migratory sensory neuropathy?

Amitriptyline seems to help, as do opiates, but not much. The nerve pain is so sharp and unexpected that its hard to treat with drugs beyond dulling things a bit. I have found acupuncture can greatly reduce the area of pain - usually a v shape branching out from where the nerve is affected, usually down the legs or arms, but can literally be anywhere you have skin, including inside the mouth or ears! Once a nerve hurts, stop what you are doing, usually that allows it time to calm down, but sometimes it just kicks off, hurting randomly for days or weeks, but then it calms down, goes numb, and slowly repairs itself, with the feeling returning to the area either totally or just leaving a small numb patch in the middle.
