Sarah, I can't help you but may I ask you? I have had RSD over a year and its in my arm and now my feet. I have recently been waking up sweating profusely(full body) but only at night. I also thought it must be meds because my Dr. recently changed them but it still happening. So you would only sweat at night too? Did you sweat all over or just the area of your RSD? I have looked it up but never have found an answer. Sorry I am no help but thanks for your info. momof4
