hi,i know this might sound silly,but it could simply be trapped wind,,as i get it alot,sometimes i feel like im going to explode,and my ribs hurt,and as u say a sence of pressure,but if u think about it,when ur gut is full of gas,ur
stomach swells,but ur
ribs dont move, so the
stomach must press against the ribs,,but u could always go to see ur gp, just to get it checked out,good luck, viv
