Okay, I am getting really perturbed at my left arm. I can barely do anything with it now. It's painful to the touch right on top of my arm at the elbow. There is a little bone that sticks up (it's on my right elbow, too) and it feels like it's bruised but I haven't done anything (to my knowledge) to bruise it. If I try to lift something with my left hand it hurts my arm. I could barely put sheets on my bed yesterday because pulling and tugging with my left arm just irritates it. What could this be? I'm resting it as much as possible and not using it any more than I have to but I'm tired of the pain. Is it arthritis? Bursitis? MS? Ughhh.....I don't want to go to the doctor and spend $85 for him to tell me to rest my arm.
