I am feeling bloated stomach as soon as I had a meal. The gas reaches even higher that I feel the pressure in the chest as well as in my throat and mouth for sometime. I have having these symptoms in some forms for some 4-5 months now. The stomach sometimes gets so tight that I can't sit if I don't keep my back straight. This troubles me during travel. I also have the feeling is like when a burp is incomplete. Last information, I had this gas problem in much lower intensity for quite some years which I recognized only now.
