My husband had three blocks -- one brachial plexus and two stellate ganglions. He had good circulation for about 18 hours after each but in the car going home his pain would go sky high. His pain was at the end of one of his scars (on his palm) but would radiate up into his fingers.

After the third block he said he was done with them and refused to have any more, but he also very slowly started to get better and today is in total remission. He still feels a "pulling" sensation at the end of that scar when he stretches his fingers straight and other occasional twinges but is free of pain and symptoms and is off all meds.

His doctor could not say whether it was the blocks, the rigorous PT sessions, the meds (3600mg gabapentin which husband says did nothing), or a combination of all. Or even none of the above!

I think if my husband were reading this and responding, he would recommend trying a couple more blocks. His doctor said he knew of some patients who had a dozen before they started getting any lasting relief.
