Andrea, My friend had this done a few monthes ago. It was extremly successful. I was scared for her because this procedure is so controversial. But it went well. She was pain free until she had to have surgery not related to RSD. As soon as she did the pain was back. They are thinking of doing the procedure again she did so well. She had pain levels of zero much of the time after the procedure. DO alot of research & ask alot of questions is my best advice. SHe is from Alabama so I know you don't have the same doctors. Good luck.
Hugs, Denny
