Abdominal pain is pain that originates between the chest and the pelvis. Abdominal pain can be cramp-like, achy, dull, or sharp. It is often called stomachache.
Burping is the act of expelling gas from the stomach through the mouth. It usually occurs after the stomach has expanded due to too much swallowed air. Burping releases the air. It is also called belching.
Swallowing air into the stomach can cause a bloated feeling, a distended abdomen, and stomachache, accompanied by burping.
