Every once in awhile, I get a pain in the center of my chest.....it's when my back is trying to go out. It is directly behind my breastbone, which seems to pull on my ribs or something. I can't take a deep breath when it hurts. My back doesn't have to actually go out for it to hurt. But when it does go out, it hurts even more. I describe the pain as feeling like someone stabbed me in the chest. Once my back goes in (or gets put back in) the pain is gone immediately.

Something else you might check into. I hope the cause of your's is found soon, and that it's something easily fixable.
