A few weeks ago I was hospitalized for SOB, chest pain radiating to my back. Completed a series of tests (stress test, EKG, EGD & colonoscopy) of which all came find. Last night I suddenly began having chest pain in the center of my chest along with breaking out in a sweat, nausea, leg weakness, headache and low grade fever. The chest pain is sharp and feels like something is lodged or blocking something. I called my primary care and he suggested the ER. Any thoughts on what could going on?
