I don't have medical experience, but I had a heart attack a year ago. This is what I felt: - Feeling diffusely sick, no specific pain, but a feeling that something was wrong. - Oppression in the chest. - Mild pain in the left arm - Cold sweat. I tried to drink some water, open a window to have fresh air, sit and relax, but after a couple of minutes nothing improved. I was at the office (alone) so I googled the symptoms of a heart attack and next thing I was calling 112 (Spain's equivalent to 911). It was a mild heart attack, I got a procedure in the ambulance that stopped the attack, and a barely had heart damage. I had a triple bypass surgery a week after the attack, because the three main arteries were clogged. So it went well, because with those arteries I could have had a more serious attack at any moment. My advice would be, if you are not feeling right and you never before had those symptoms, call 911 (or whatever the number is in your country). The people that picks up the phone are trained to assess the calls, and anyway it's better to raise a false alarm than to die.
