Hi Angie, Sorry about your experience with the block. I, too, had a bad experience with my second block. Not only was the pain of having the block unusually painful but immediately following the block I had terrible pain in my groin for an hour afterwards. Since the 2 blocks I had were not effective in controlloing my rsd I decided against having any more. When I told the docs they wanted to do a sympathectomy but I said a BIG NO to that. You have to weigh the pros and cons for yourself and decide what is best for you. But, please don't allow them to pressure you into anything that you are not comfortable with. My best to you...Jeannie
