Hi, I Feel Like Something Is Loose Below My Left

Hi, I feel like something is loose below my left rib and now it has started to hurt more often. Also I feel like it is messing up my bowels. I wake up bloated and stay that way all day. I can't physically feel anything when I touch the area. I am taking iron for iron deficiency anemia. My last CBC was good. It is making me city constipated though.
