Debbie,
I had 3 SGB's and they helped me a lot. I couldn't have as many as was needed do to a bad reaction but the ones I had were a blessing.

Some people say they don't do any good after you have RSD for so many months but I know better. I had a friend that had RSD for 30 some years and I talked her in to going to my Anestelogist and she called me up and said it was the best thing she ever did. She couldn't believe how good she felt and she was on so many meds at the time, she couldn't stay in her chair.

Have them done, I bet you won't be sorry.

Good luck,
Ada
