I don't have GERD, but I was diagnosed with Gastritis in January 2013. I'm 80% better but still having some trouble. A few days ago I started getting the pounding heartbeat again that I was getting when I was really sick last year. It's not anxiety, as I'm not under stress and I've actually been pretty happy now that my stomach has been feeling better. The pounding heartbeat is accompanied by a tight, almost "buzzy" feeling in my upper stomach down to my intestines, and some burping and general discomfort. Also some urgency to do #2 but no diarrhea, just a little "mucousy" (sorry for the details!). The heart pounding gets worse with any physical activity, like my heart can't keep up, almost the way you feel when you have the flu although I'm not sick.
Had heart checked last year when this happened and everything was normal.
Doc said it's probably anxiety, but I don't think so. I've had anxiety attacks before and this is different. It lasts all day, from morning to night. I feel it's related to my stomach somehow, like pressure from my stomach may be pressing against my chest wall? Or it's like my entire GI system is has anxiety but it's not related to my mind (at least not consciously).
Xanax makes it all better, so maybe it is some kind of "nerve" component in my GI system? Of course I'll only take Xanax if it gets really bad which it hasn't been, just very uncomfortable.
Has anyone else had this symptom?
