Any time they preform adominal surgery they fill the abdomen with a large amout of air to seperate the oragns. When the body passes this air it is very uncomfortable. In fact it is down right painful. This should pass and be over with about two weeks or less after the operation, The pain is intense enough to put you on the floor in fetal position. This is normal in most surgeries. If you are getting more than this I suggest you contact you doctor.
