I'm due to have a stellate ganglion block on Tuesday to treat RSD/CRPS Type I in my left arm. The RSD/CRPS is located from my left shoulder blade, down my arm to the border of my hand/wrist. I've had RSD for 9 years, but I was in remission for 7. It came back in my arm in April. The pain was starting to back off a little, but it during the past week, it's increasing again. I've been out of work since May on short-term disability through my workplace. I'm supposed to go back to work on Nov. 20th. Will the stellate ganglion block be effective enough to allow my return?

I had a lumbar block 8 years ago to treat my first bout of RSD in my left foot. After 2 blocks the RSD seemed to go away until this past April when it reappeared in my arm. Because it's a different body location and different block site, I'm concerned I won't get the same kind of relief. As my return-to-work date nears, I'm worried that the block won't work and won't relieve the pain enough to allow me to function at work.

Does anyone have any experience with this? Any advice?
