Lately I get this staticy feeling in my back on my right shoulder blade.. I don't really know how to describe it, but do you know the feeling your skin gets when something is sticking/static to you? That's what it feels like but I know its not static because it feels like that all the time even if I have nothing on my back.. once in awhile it will hurt and send pain down my right arm to my wrist. But its never really bad pain. Very mild. It's just annoying...
