I have some kind of ATN (they think). I get pain at a sustained 10+ for days. Its most likely a neuropathy from my MS. Anyway, I'm a big believer in meditation, relaxation and biofeedback. I use them to manage my pain with migraines and my facial pain. That's exactly what pain management clinics do. Try contacting "alternative" therapists who might be listed under things like "biofeedback training" and "relaxation." In So Cal these tend to be licensed therapists, psychologists, and counselors, so insurance coverage, etc. is different.

Just thought I'd suggest it, though.
