Christine,
I would love to give you some info. but I've not had one done. In fact, as it has been determined that I have had rsd for well over 2 years, my PM said blocks will not help. He indicated that he will go to scs as the treatment choice. I will find out more on the 12th. I have to be honest and say I'm really glad I don't have to have the blocks. it just seems that everyone who gets them ends up really hurting. I hope your pain subsides, and it gives you the bliss that I know others have had from it. In the meantime, pamper yourself, take your meds, and try to sleep.
Mary
