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.
