A year ago I was working out and began to have joint pain is knee , elbows and muscle spasm in my legs sporadically I suppose from over exertion?. I went to therapy and also been taking medicine for the swelling. Although the the meds worked for a small time, I know have a left knee with so much pain and stiffness and barely can walk now. Many tell me its more than that...but no doctor can seem to help. I am trying not to have a cortisone shot, what can I do?
