Hello, this is my first post on this forum so I'll probably get a lot of things wrong. But anyways, since probably a year now I've been experiencing random (most of the time) moments/episodes of feeling a burning sensation in my chest/stomach, as well as sweating a lot and a pounding heart usually for no reason, other times something has happened that should not affect me so badly. So basically I am wondering if these are anxiety attacks or have anything to do with anxiety or something, or if its something else?
