Hello, I've Been Having A Lot Of Gas (burping) Anytime

Hello, I've been having a lot of gas (burping) anytime I drink anything. In that, I get these random "air bubbles" in my upper middle chest area and almost in the throat that I think is coming from the stomach, as I have seen cardiologist and the EKG, Echo, and Stress Test came back normal. Have had some tingling in the gallbladder area off and on when I eat too much. Trying to make sure the "air bubble" feeling is coming from the stomach and ways to get rid of it.
