Question: I'm 29 M. I have this pressure or blockage That im assuming is a trapped air bubble on my right side under my ribs about an inch or so below my nipple. Very small area the size of a quarter. I've also had this feeling at an upper part of my lung as well but not as often. It causes my heart rate to speed up. The more pressure/resistance i feel the faster it gets probably no more then 120bpm. Sometimes I get a fever and hot cheeks just before heart rate increases also. I can burp the small amount of air out eventually (I feel better almost immediately) but it's just replaced by more air 30 seconds to 5 mins later. The pressure is always their but its the build up of pressure that gives me issues. When I do burp it feels like coming from my right side lung not up the middle of my throat like a normal belch from a meal. 

I've been to the hospital for my heart before for tachycardia. Didnt have this symptom. I've learned to deal with it rather than medication. They said my heart is fine and believe it is also. In the past it would happen on it's own for no reason. This feels different. Like air bubble is putting pressure on something making heart work harder. This seems to be causing my increased heart rate. 

Ive been trying to see if its cause by anything. So far it seems to just be their on it's own accord. I feel the best laying down. The pressure ocures randomly throughout the day mostly when sitting up or standing still though it has happened laying down as well. It has happened before before my first meal of the day. So it doesn't seem related to what I eat or when I eat. I feel completely fine at first, then a slight pressure, then even more pressure when issues begin. 

I've been researching online coming up short. If it was something intestinal related would it cause air to build so high in my chest? The air comes from my lung not stomach and only my right lung.
