Newbie here...just diagnosed in February, 2006, but suffering since 1996. I just have a really quick question: I have a bruise-like pain (no hematoma visible) to the right of, and behind, my left shoulder blade. My left deltoid feels like I've got "icy hot" applied to it, and from there down, it feels like I'm wearing a pumped-up blood pressure cuff, with my left hand looking red and swollen, and cold to the touch. There is no numbness present, but I do feel a slight bit of weakness. With the obvious "go to the doctor and find out" mantra out of the way, does anyone know what this might possibly be, and should I be at all concerned? Thanks in advance for any and all constructive comments and/or answers!
