Yes that is exactly what it feels like, right below breast level and is even worse if I lie on my side.
At its worst almost always accompanied by burping - BIG TIME. I guess the good news is that I have had this for going on 4 years so probably not a fatal problem but so very uncomfortable and utterly baffeling as no doctor has been able to figure it out. I had my gallbladder out. had an ultra sound, a cat scan, an upper GI and nothing. Anyone with any idea would be a godsend to me and would have my everlasting gratitude. Thanks much.
