@lotsofpain, have you had any imaging done or talked with your provider about the pain? Did an injury or accident cause it? I had pain in my left shoulder due to some of the same movements and it was thought to be a pinched nerve (which was there but wasn't the whole problem). I ended up having MRIs, but when the surgery day came they found a torn rotator. In the end, muscle/tendon injuries can be difficult to diagnose. Does yours ever hurt when you are not moving it?
