I have been getting weird burning pains all over my body, particularly in my arms and forearms and arm pit area... But I also get the sensations in my thighs, legs, and shoulders. Even in my backside. The pain seems to go away when I'm active and I notice it more when at rest.

I have been told I have TOS but that would seem to be illogical for leg pain. I don't have any swelling or color change. And cold doesn't seem to make anything worse. I haven't lost range of motion either. Just a constant sun burn pain and small areas of skin that are hyper sensitive at times.

From what I've read about rsd that wouldn't seem consistent. Any thoughts? The spread in a matter of two months to my entire body seems inconsistent too no?
