I have problems in my shoulders, wrist and hands, knees, and hips. When the flair up starts its like, (which ever part of my body that it affects), it starts just being sore but about 8 hours later it turns into the worst pain that you can possibly imagine. The pain is so severe that I lose the ability to even move. This pain normally last about 24 hours, then just like it came it goes away just like nothing ever happened, no pain or anything remain. What could be causing this?
