Hi I am having spasms about at the point of my breastbone I can feel it starting it gets worse and worse I can feel the pain go straight thru to my back,,this happens mostly on a empty stomach and I drink water then bear down and try to burp real hard and that seems to stop it,,,it hurts bad what the hell isit? I don't have gerd or not that I know of No reflux or sour stomach heartburn,,,none..I have been on opiates for years for sever back issues,,maybe that is doing damage?
