question: Hi, over the last few month I can feel there is something below my left lower(last) rib cage. Its not really a pain but is irritating me of the reason. It comes and goes.earlier i used to have bad stomoach quite often. I consulted a gastro recently and he suggested me IBS and prescribed med(riximin, ibset, anleo, inlosa). I have taken these med for over 20 days now; though the pain has releived a but but still i can feel there is something. My stomoach has relaxed now and my stool has stabled, about 3 times a day. I am stressed if there is anything serious. Please advise
