Hi Kimmie, there is one thing more to consider. I was determined to have RSD and had gone through a series of blocs too. I had a vascular surgeon that diagnosed it and he steered me into a sympathectomy, that is an operation where they went through the stomach with a 6 inch cut and cut the sympathetic nerve on the inside of the spine. This was in 9/11/06, about a month before that, a letter was published stating the dangers of said surgery. It said that it was an invitation for the RSD to spread, It had a high risk of creating more pain that it's worth, and the most important, it eliminates any possible repair to the nervous system involved because of the finality of cutting such an important nerve. I see they have been allowing Doctors names to be dropped here, I would do some thorough reading before having the surgery I had! I would have checked Dr. hooshmands findings sooner. Wish ya the best Kimmie! good luck, Laurin
