Since my IBS pain is on the left side, sometimes I get the feeling as if something is stuck inside me. It is not all the time but depends on what movement I make or whatever. It just feels like something is stuck there on my left side, it somtimes can me just under my ribs or all the way near my belly botton. That is what gives me the fear that a tumor/obstruction maybe there....Also I useally go to the bathroom most mornings after my coffee just fine, some mornings though not till a hr or so later. When I do not go right away there feels like a build up in my stomach like it builds and builds and then finally I go...Just curious if anyone else here has these feelings.
