I have a very sore shoulder and have been told I need shoulder replacement surgery. It would be the only way to repair my shoulder. I was not feeling this was right for me. I also have a knee that I was told needed to be replaced. That was a few years ago and I have not had that done either. Both of these joints are very painful and the shoulder is a new occurrence, just since December, this was when the severe pain started and the lack of motion started due to pain.
