What Causes Excessive Bruising And Bleeding Inside The Groin Area After An Angiogram?

My husband had an angiogram done on the 16th. They went in thru the femoral artery. He was told that brusing is normal in the groin/nuts. He is still having some pain where they went in, but is it normal for his nuts to be excessively brusied and painful. Is this something we should call and ask his Dr. about? He has a follow up the 17th of July, but I am sort of wondering that it may he may be bleeding slightly under his skin, and, that it is not brusing but blood under his skin in the nuts. I am leaning towards calling his doctor. There is no lumps/bumps where they did the entry, just some pain and lots of brusing all over his nut sacks. I was not aware this is something you have to pay for to get an answer. Sorry, I am not going to do this, I will just call his doctor tomorrow, I will not be using web md or any other site where you have to pay to get an answer to your question/s Thank You for your time anyway.
