hiya ozzies - and on that last post, mjh, let me just say OUCH
I saw a dude on our high school footy team suffer a similar injury. He got tackled and someone stomped on his nuts, but he didn't feel it. Stood up, someone pointed out that his white shorts had gone red. So he dropped his dacks and one of his testicles was actually hanging out of his nutsack.
He passed out and they took him off to hospital. Thirteen stiches later his testicle was secured back in it's proper position. Bet he's got a wicked scar though.
