Sonny1, I am glad to hear your blocks are going well. I remember how terrified you were before the first one. My husband had three (for his left hand) which he felt didn't do him any good, but something must have "clicked" somewhere because he is now in complete remission (knock on wood). Hang in there and keep doing as much PT as you can. Husband thinks it's that more than the blocks that helped him. He still does his exercises and it's been over a year since he had any RSD symptoms.
