|Hi. I am trying to find if someone has any idea what causes a sharp sudden pain like something is pushing out of my rib under my breast. I move and sometimes I get this catch that is very painful. It is something like something is pushing out of my rib and hurts tremendously. I have to grab under my breast and rub it like I am pushing it back in to get it to subside. Sometimes I just turn a little and it happens. It seems to come more frequently now. My daughter said it is gas pockets can someone help me.
