I suddenly just had the urge to go the bathroom and had a sharp pain shoot through my chest up to my neck. It was worse when I breathed deeply. It actually radiated to the back of my head. I went to the bathroom, everything was normal. I threw up because of the pain and I was a bit nauseous. It has now subsided but it scared pretty terribly. I've been diagnosed with IBS and GERD and have felt similar pain in my throat before.I have no headache, no problems breathing, no dizziness, no headache, I'm very coherent andcurrently trying to relax. I have not been diagnosed with any heart related problems. I'm 22, 121 lbs, fit, supposedly healthy (my doctor has said).
