Ok some background. I was starting to work out take vitamins, whey protein, muscle milk, protein blend, creatine, and some NO booster. After two weeks, I started getting light headed when I worked out and stop. That was last month. Now, while I was walking in the street, my heart had 3 irregular heartbeat in a row. This scared the crap out of me and caused a panic attack. Before that, when I walked up the stairs (5 flight), I will kinda get chest discomfort. Now I am getting worried. I am uninsured. Should I got to the emergency room ? what should I do ? Also, when I was a baby, I was diagnosed with a harmless murmur. But as a young man, I never had trouble with sports (I even ran long distance in High School) I did stop working out and stop taking all those supplements.
