I had it and a friend who is ten years older and looks ten years younger and in fit shape said, it takes years of oversue and abuse to damage your muscles and cause that much pain. Try this over the counter Vitamin E and Selenium TOGETHER every single day! You won't notice at first, but in a few months I realized it when someone offered to help me carry a heavy basket because of my pain in arms (I then realized, my arms didn't hurt at all anymore) It did work for me. Thats all I can say. It never came back.
