I've been having chest pain in the center of my chest that goes straight to the middle of my back. It's painful, but not excruciating. I also break out in a wash of sweat with it. I've had it before and been checked by a dr and they didn't find anything. I've had costochondritis before, but I'm not sure if I had this kind of pain with it. I have lupus, RA, fibromyalgia, all active.
