Hello Cynthia~It sounds to me like you could have a very bad case of
gas,
gas can get trapped under the ribs and sometimes even lift them up a little, I know, I speak from experience. Does this happen only when you eat, or do you have it with you most all the time?
I would try taking some activated charcoal, you can get this in a capsule form from a health food store and it literally draws all the gas out of a person, also, try some digestive enzymes, again, obtainable at a health food store.
