well there's honestly no way to tell without having a physical examination. however common sense would say a more likely cause of abdominal pain would be constipation not pancreatitis. constipation is much more common. chances are if you had pancreatitis you would know it. you probably would go to the emergency room since acute pancreatitis not only is very painful but usually causes nausea vomiting and a fever. if you have upper abdominal pain that doesn't go away and is accompanied by other symptoms (like fever and vomiting) your best bet is not to try to self-diagnose. go to an urgent care for a diagnosis. wishing you well!
is it constipation or pancreatitis
