I had a really bad attack last week end. I had major heart burn but not like ever before. I vomited but no bile or food just massive amounts of clear mucus. Is that something you can experience when having a heart attack. I was sweating profusely had to change my clothes. When I laid down I had the most excruciating contractions on both sides of my back and at the same time I had the worst pain in the center of my chest it was like the worse heart burn really major pain several times. I could not even talk it was like I was out of it. Couldn t eat the next day or stay awake. I have had pain on the right upper rib cage, right side and my right side of my back and it just keeps getting worse. I have been taking morphine vicdion. I have gone through all the symptoms and I have them all. My questions are is mucous vomit common with heart attacks do you think I had a heart attack?
