I have had a work comp injury to my back in June of 08 and they dont find me to be a candidate for surgery. I have two bulging discs and real bad nerve pain in my right leg. I've had multiple shots and PT for a few months nothing had worked. My leg pain is so bad I can't walk w/o a cane some days and not at all some days. Anyway my surgeon wants me to try a pain clinic. I don't really understand what they are about and was wondering if anyone has been to one to tell me what they are about and how helpful they really are.
