First off try to realize that the stress is part and parcel of the RSD. Try to stay calm. Of course you won't be wholly successfull.

The block often work if done early. You have about a two year window before the chances for a remission start decreasing. I had no pain from any of the blocks but some did seem unnecessary. I did get a slight RSD spread to one of the injection sites but it's about the least of my problems.

Do everything you can to get rid of this and try to remember it's not the end of the world if you can't. Hang in there and fight it.

Best of luck.
