Swelling: I think you should see a doctor to get a definitive diagnosis. It may be accumulation of gas in your stomach. You may want to try an H2 blocker or an antacid

Needs to be checked: You symptoms suggest you may have medical problem with your stomach like an ulcer or chronic gastritis.Or it may be from your Gall Bladder.Swelling under the rib cage may be distended abdomen or a lipoma or Ventral Henia I suggest you make an appointment with your Doctor and get checked Need a detailed History and Physical Exam and if indicated some tests like blood tests and imaging&GI referal
