How long does a hematoma last after having heart catheterization? - hematoma more condition_symptoms

I developed a large bruise on the thigh after a cardiac catheterization. For more than three weeks, I received a transfusion of blood and I'm on iron supplements. Nothing seems to help, they will disappear. The doctors have tested and not an aneurysm, but I still worry that not fast enough to heal. Ideas?
