I have this simmilar experience too just as these guys giving their situtations on the net, my problem is I get irritated often times I hear clicking deep within my chest whenever I take a deep breath this comes sometimes with what they call a heart burn and it annoys me a lot in
the past 3 years. I got a check up
; X-rays and ECG'S and the result was normal, the doctors diagnose it with an atypical heart block but my second reading was normal. so what is this?
