The pain started over a week ago, more so in my chest, and a little in my back. It went away, then one day at work I noticed my back starting to hurt around my shoulder, on the right side. The more I am up, walking around, or even sitting up, it hurts. Is there anything I can do to help it? I don't know that the Dr would be able to do much, as it seems to be a muscle problem, but wondered if it sounded serious enough to go see one anyway.
