I go see Mr. Twister with his new "license to hurt" on Thursday so I'll let you know how that goes. I don't think he has to break up any stuff in there, like scar tissue, etc. It is just some muscles that were pretty much in one position for a long time and need to lengthen and become strong again - by stretching and slowly adding resistance. Just when I think my arm won't go any further in a certain direction, by gosh the next day it does ... maybe just a little, but it does. Like today, I finally could reach out and pull shut the car door! First time!
