I noticed that my left rib cage sticks out much further than my right, with this I have pressure. Not pain just lot of pressure like something is pushing it out. I have tons of indigestion and sometimes acid reflux. I've been to the doctor but she told me she wanted to get all the test that I've had done and then see where she goes from there. I have had a ultra sound about a month and a half ago of my liver and gallbladder and everything checked out fine. I experience yellow stool a lot. I noticed my stool went back to normal cutting out gluten. However I found out gluten was in a sandwich by "mistake" a few days ago and now my stool is back to yellow and the pressure under my rib is there. Any idea what it could be?
