I have had 3 in the last 10 years. Treat it like a surgery. Do exactly what the doctors tell you. If possible they can go in through your wrist. Less recovery time. If you have high BP they may keep you overnight. Took me 2 weeks to recover from the first one. The second and third one was a little better. Ask them for a sedative before the procedure. Takes the edge off. If he finds more than one blockage he may do the first one and the other later. Reason is the dye is hard on the kidneys. Hang in there.
