Welcome to Neuro Talk. I am sorry that you suffer with this RSD. I don't have the same condition, but I do understand what the illness is, and have empathy for what you endure. There are alot of folks on NT, who will be here for you. More research needs to be done, thats for sure. I don't even think the doctors really know what exactly triggers it. It seems it begins with some kind of trauma to the body. I hope alot of people respond to you. The SCS has helped many to cope. I wish there were answers to this Beverly, that it would just clear up and go away. I am glad you found some doctors willing to help you with it. I will be thinking of you, and keeping you in my prayers. ginnie
