Catra, my dr told me that doing procedures that cause more pain could also possibly cause spread. Is there a way you could check with your dr about that and see if he could give you a note stating that so that they don't put you through that again. I am not a dr and am not trying to tell you what to do, I just don't want to see you in anymore pain or have spread because of tests that you were told to do to prove you are in so much pain. I would like to think that if the people giving you these tests realized the further damage they could do to your health, then maybe they would think twice about putting you through these horrible procedures. I just hurt for you. I don't want to see you in anymore pain then you are already in and I don't want you to get rsd spread. I may be wrong but am just worried about you. Hope you feel better soon. Hugs.
