After eating lunch, I was fine didn t have anything I haven t had before, I had severe constricting pain to the point I took off my bra, broke out in a sweat, couldn t breathe and almost passed out it hurt so bad. Called Ambulance while I went and layed down, they got there and ran a 12 lead EKG, results were normal. After a little while felt better but not normal. Got home and started some laundry and the pain thing started all over again. Still hurts but not like it did and still not feeling normal. Should I be worried?
