I have really bad burning in my upper chest that always begins with belching and burping. This pain feels like acid burning my esophagus and it is very atypical because I only have it once every 7-12 days. It is also atypical because it always last 24 hours and then it is over until the next 7-12 days. I have been to several gastro physicians who have done all the tests and say I only have a slight case of GERD. Can this be caused by my gall bladder? I need some answers because when it is active, it really hurts!
