My husband was working really hard the other day lifting and moving some things that were pretty heavy. Well a few days ago we noticed he had blood and a foul smell coming from his belly button hole, so I took a flashlight and q-tip and looked and saw what appeared to be either a hole or tear in the lining of his belling button right at the bottom of it. So I cleaned it and he has been taking it easy so as not to make it worse. What do you think this is and what would you suggest we do?
