Just when I think I am managing my pain quite well except for the discomfort caused by using my treadmill only for one day, I now am noticing that I have been having clavical pain for about 3 days. This couldn't possible be from using the treadmill (at least I don't think so). Sometimes it almost feels like a choking pain. What next. On another web-site I observed that there many other PMR sufferers that complained about clavical pain. I always thought PMR caused hip, leg and shoulder pain which I had before being put on Prednisone. I have been on Pred 2 mg for about two weeks now. Does anyone else have clavicle pain?
