I know it is gas because when i hit my side or pound
on my back i can create a burp.
the gas is very painful and can travel through my body to different parts causing very strange symptoms. I can create a burp within a few seconds by hitting my back with my hand ( like burping a baby) The gas can be in my side, middle of my back, hips, etc,, sometimes it feels like my lungs hurt but i can tell it is gas.
