Hi, My Husband Had An Angiogram Done 10 Days Ago

Hi, my husband had an angiogram done 10 days ago and there has been some bruising that has increased ever so slowly the past few days very close and to the bottom of the groin. The very dark bruising has been spreading slowly down the upper inner thigh area about the size of a hand. He only had a small amount of bruising the first few days after the procedure, but it seems the bruising has gotten more pronounced 10 days out. There is not necessarily any lump or increased swelling to any particular area, but maybe just a little puffiness to his pubic area near the groin that the angiogram was done in. Appreciate your input. Thanks
