I had a heart cath three weeks ago. It did bleed post op, I became very ill. the day after. I had a very large hematoma and through a ct scan they found quite alot of free air in my groin and suprapubic area. After waiting one week, I ended up in ICU, then went to emergent surgery. Can you tell me what possibly might have happened. They opened up my groin and placed a Penrose drain. I now have at least 7/10 pain and have an extremely large very ropey hard, painful lump in my groin,
