I think all I can say is WOW. That was alot of information. It explains alot. First, I had the rib resection and yes my right shoulder droops. My bra strap continually falls. I used to keep putting it up but don't bother anymore. Noone sees it anyway. I'm going to print this for my neurologist. He kind of defers to Dr. Togut and he may find some of this interesting and useful Thanks. Linda
