Whipple procedure and blood pressure problems

Is there any whipple people that have probems with blood pressure, and allergic to that medicine.  Also Has anybody had problems with a pain that comes fast and you end up on your knees or the floor and then its gone.  It feels like a heart attack, but its not,  and the doctor thinks your nuts.  I think doctors think patients are stupid sometimes and really take the easy way out and say you really don't have a normal body.  I sit there and say to my self no _ _  _ _.    Waiting for reply's
