Had ablation last Wednesday, all clear and came home Thursday. Saturday morning noticed a small, about the size of a small grape, hard lump in my groin above the puncture site. I was told by the hospital to apply pressure which I did and it seemed to soften. This morning it has returned and is now the size of a walnut and quite tender. A bit worried about it. There is extensive bruising this time which I didn't have after my first ablation.
