Im 25 yr old female, 130 lbs, 5' 3", I had a gallbladder surgery when I was 16, and I a few years ago I started with a bad case of belching.. I do it ALL the time, in the morning when I wake up, while Im at the gym, it really bothers me.. nothing hurts, its just constant burping, and sometimes I feel like I have that gulp of air stuck in my esophagus, and I just cant get it out.. I have to force the burp to get rid of that discomfort.. Idk what this can possibly be, I dont believe it is acid reflux cause I have no pain, or maybe indigestion?
