More or less what it says on the tin. For years now I havn't been able to actually produce a solid burp. Instead it comes up more like sigh. If I drink a soda or something similar, I can then burp. But if I'm laying down or even just walking around, instead of an actual burp, it's just like exhaling a second breath that comes out of nowhere. I've also noticed that in general I tend to have more "Upset stomach" pains, like feeling bloated or like I've got trapped air in my upper gut. It's torment. I know burping is "Uncouth" but I mean hey, you gotta do what you gotta do.
