I'm having issues with my left side. When I lay on that side my hip has a burning sensation. On the left side of my knee there is an area that is sensitive to touch. Just rubbing it hurts. At time my left arm has a dull pain as does my left leg. Also, my left ankle hurts pretty much all the time. Sometimes it gives way completely to where I can barely put any pressure on it. It seems to be getting worse. I'm tired of popping pain pills for it. What is going on?
