Actually I was just diagnosed so haven't had the opportunity to do that. good idea though. from what I've read causalgia's main symptom is swelling and or redness of the skin. I have never had swelling. I really believe it is TOS. when I was first told about TOS I did some research on it and just started crying! My symptoms are textbook! I was so relieved that I finally understood what was going on with me. however now I'm at an impasse...waiting for some kind of treatment from the docs. none of them have given me any indication as to what to do next. have a pain management appt. but its not until Dec 13. Really feel like I would be better off without my arms right now!! I apologize for the whining, just overwhelmed from the pain
