I had a 'frozen shoulder' years ago. They never knew what caused it but it got to the point I had to have it surgically broken loose. They did not break the shoulder, but just took ahold of the arm and "broke" the shoulder cartlidge(sp) loose. When I woke up it was above my head and I had to leave it that way for 12 hours. It was painful but I have not had any trouble since. I would say "do it" but plan on some pain for awhile afterwards while it all gets back in place. I'll keep you in my prayers.
