Welcome Flora,
Sorry for the circumstances that bring you here. This is such a wonderful group of people. We're the only ones who really understand this monster. However, all we can is offer moral support and advice to one another.

Not only was my broken wrist surgery screwed up I got RSD/CRPS as well in my hand and arm. They refuse to do further corrective surgery. I don't know what I'd do if i needed surgery elsewhere. My P.M. Dr. said she would probably give nerve blocks before and after surgery and hope for the best. I also take Vitamin c 500-100 mg. to help prevent spread. My RSD beast is kept pretty with nerve blocks for right now.

Tough decision for you I know. When I went for colonoscopy I was worried if they had to cut out any possible pollips. That Dr. told bluntly that the RSD probably won't directly kill me even if I wished it would, but colon cancer would.
Thankfully no cutting was necessary.

Please keep us updated.
