I totally know how you feel. I have a feeling all RSD patients do. The last pain doc I saw told me he thinks it is just tight muscles... yes 1.5 years of hand burning, aching, temperature changes and swelling must be caused by tight muscles in my neck... that makes total sense why didn't I think of that...NOT!
Hang in there! I hope you find a good doctor that truly understands what it's like to have RSD or at least be willing to listen and learn.
