I have a ruptured C5-C6 and now am told I may have TOS. I was in a MVA in '94 and have had a lumbar fusion, and three spinal surgeries before the accident. Now waiting to see a vascular surgeon. Also have a friend who has RSD. Hve you consulted a oain specialist about an implanted morphine pummp? It delivers the Morphine directly to the area of pain so you don't have the side effects of the morphine going through your entire system. Good Luck and God Bless.
