Thats right if you spend anytime with chronic pain patients you will find that while most respond well to med's others respond to acupuncture, hot tubs, weed, petting their dog or whatever works. A friend of mine had bad pain in his right arm he went through every treatment in the book, they found via biofeedback that the problem was a nerve in his left hand...figure that one out, they think his wiring was screwed up or it was purely psychosomatic.
