I believe you are saying that
the pain occured when they closed
the entry site six or seven hours after
the procedure? That can be painful, at least in my experience, actually quite painful, but certainly something most people can handle. I've had a number of angiograms, some are painless, some hurt, but it goes away. Is there swelling, bleeding, or as kenkeith mentioned, do you have a fever? If so, I'd sure be contacting your doctor.
