A few years back my hubby had a dbl hernia repair and his penis turned bruised... The nurse had put the bandage on and somehow cut off his circulation.
Hi and thanks for using the forum.
You should call your surgeon just to be sure, but it is not uncommon to have some bruising and swelling after surgery. Cool packs to the area can help. Also, when lying down, propping your testicles up (like on a rolled up towel) can help reduce the swelling.
Hope you feel better soon.
