For over a year now I have been having occassional fast irregular heartbeats then my bp is always normal and heaviness and so much discomfort.from my throat to my right breast.once a month I feel sharp chest pain just before my right nipple.the discomfort or pain sometimes get to my rightback side.it feels like something is stuck in my throat.and as if I get a little relief when i let out burp or bubbles from my mouth.i have done chest xray eco and ecg and even mamogram which says its a normal result by the grace of God
