Hello! I occasionally have pains in my chest, not just in my heart. But I just had a pain that concerns me. On my left side about 4 inches from my armpit there was a sharp stabbing pain. When I inhaled there was another stab and when I lifted my arm straight up and leaned the the right it hurt. The pain has left, but now I have a slight headache. I am healthy besides asthma so I have no idea what it could be. Any suggestions?
