So, I decide that since I've been getting faster beats, acid at times and all the breaths etc etc. It might be a result of reflux? I was on tablets for it for a year ago...I mean, this feeling has been going on/on off for over a week now! So I doubt it's anything to serious and I had a 10 hour shift mainly standing today...so that was a work-out on it's own lol and I know it's silly to say but when I was wearing my headphones I could hear my on heartbeat super loud in my ears and it was rather unsettling lol
