Is groin/leg pain a few days after a heart catheterization common?

Yes: Yes, this is fairly common and will usually resolve over the next two weeks with no intervention. However, rarely damage to the artery at the groin site can lead to a fistula or recurrent hematomas and if the pain persists it should be evaluated by a doctor.

Yes: It is a common side effect. However, if the pain is severe or does not improve, or of here is severe bruising, it should be assessed by the cardiologist.
