I've been having left arm pain for a couple months now. Somedays its worse than others, today for example. The pain starts at the shoulder and ends at my fingers. It hurts at different spots (not all at the same time) it worries me because I think it has to do with my heart. I don't have other symptoms with it. I just think of it too much & I feel as if my jaw hurts too. Does anyone else feel this? What can I take for it?
