Everytime after I eat something I get cramps pains . I get this really sharp pain under my rib left side . It's super sharp and I still don't know what it is . I have frequent bowel movements usually 1 hr after I eat food . And that sharp pain happens 30 min after I eat food . Please someone help as if this is just one of the many problems I'm going through . I'm only 16 and worried sick .
