Welcome Sue, I am Sue too. Just wanted to let you know you are not alone. I have sharp pain also, without a rash, but I do have swelling. I hope you can find as much comfort in this group of great people as I did and still have. I am not on that much but when I am, just reading what everyone writes makes me realize that I am not crazy and am not alone. I have been a pain specialist years ago and heard him tell the intern that I was a hypochondriac. This was before the bone scan proved I had RSD. It was very heartwarming to hear a pain management doctor say that. Anyway, welcome and I know you will feel better (not without pain) but with a lot of support from this group.
