Ever since my GM started I've had this annoying pain in my back. It's deep in my back, not any muscles on the surface. It's located in my back on the same side of my GM breast and right around or below my shoulder blade. When I look at my back in the mirror I can almost see a circle area on my skin that's kind of whiter in color, its gard to see or notice the circle but if I'm mot imagining things, I do see one. Does anyone else have this or know what it could be from?
