As a possibility, it could be reflux/acidity in the stomach. You could try Zantac to see if that helps.
But, you should call the doctor anyway and say you're not in a good state with upper gastro pain.
He should have you come in for a blood test and to manually feel that area to see if there is any distress.
He shouldn't have any problems with your concerns since he brought the possible pancreatitis initially.
Call the doc....keep us posted.
