Hi, I m feeling quite a discomfort in my heart right now. I have palpitations and a slight pinchy/greasy feeling in my heart too. I also feel some very slight pain all around my body, as if i was doing exercise. I also have a headache and I feel lightheaded. It all started 3 hours back when I over ate, basically I had a triple cheeseburger with fries and a coke and also a bit of leftover Chinese food. Will I stop feeling this soon? Maybe in a few hours? (I m only 15 btw, and this has been happening quite frequently, especially when I have fast food, which is like almost everyday)
