I have had three series of Stelate Ganglion Blocks and they worked for me. They were a temporary vacation from the pain. I had ten blocks at a time each time. That was in the beginning 89-90, 91, its been 20 years of RSD for me but, the blocks may be the same.I do hope you get some relief. Keep us posted.
