I don't mind answering questions about what I have learned the hard way about shoulder injuries. I tore and damaged both rotator cuffs--lots of arthritis present too. I have had to relearn how to move with reattached biceps--getting dressed is a major accomplishment after therapy begins ! Fine motor skills are the last thing that I can do. Just sitting to sew has been a hard thing to do. I am working on lengthening my time at ANYTHING. Therapy can only work on larger issues and time may be as important as therapy !
