My wife did and it wasn't a good experience for her or me. A matter of fact it was one of the worst experiences I've gone through in the 10 years of helping her with her RSD. I forget the name of the pain center at Hopkins, it was a family name and I also forgot the name of the treating doctor. I believe it began with a C. I've heard however (on this very site) that doctor was deemed incompetent and released from Hopkins.
