However, I just wanted to know
what severe
heartburn can
feel like. And how do I know if my symptoms are severe
heartburn and not something like a heart attack? I never have any major pains in my chest, usually discomfort and burning pains. My heart also feels like it is going to beat right out of my chest and it occasionally flutters, the latter happens when I am lying down. I also get a weird metallic taste in my mouth whenever the symptoms really flair up.
