Okay, something very strange has been happening. Yesterday, I had what felt like a knot in between my rib cage. it hurt so bad it made me ill, when I got sick and even now when i sneeze i get a shooting pain across my chest and down both arms into the palm of my hands and they ache for a least five minutes or so. The pain below my ribs comes and goes but remains achey(sp?). Has anybody experienced anything like this?
