Ten Years Ago I Was Diagnosed With Acute Pancreatitis As

Ten years ago I was diagnosed with acute pancreatitis as a result of gall stones. I was 45'ish, fit, generally healthy, non smoker and only drank occasionally. My symptoms included excessive burping. Eventually my gall bladder was removed and this cured the condition. However, since before xmas 2015 I have suffered excessive burping again with an uncomfortable but not painful feeling in my abdomen most noticeable first thing when I wake. My abdomen also feels quite hard. Appetite, urine and bowel movements seem normal although I occasionally feel full having not finished my meal which is unusual.
