Strange happening. I have pancreatitis with having a Whipple procedure done 4 years ago tying off a large tumor on my pancreas. Because of this I am now a type 2 diabetic with high blood pressure. both stemming from the surgery. Recently, within the past year, I was put on lisinpril. Because of financial reason's I stopped taking the Lisinipril but just recently seeing a new doctor I started taking the lisinipril again and after two days have experienced severe pancreatic pain. Finding out by way of my son in law going into emergency and finding that he too has the same conditions and is taking lisinpril. Doctor's told him Lisinipril should not be taken by anyone with severe pancreatitis.
