If the itch was there before your accident you most likely need need to shower better and keep your balls dry. (That’s why I wear boxers for better air flow.) Google “nut sack itch” to find out if you need to see a doctor. I use a $20 Nerolco electric body groomer and still occasionally get a nick. Google "men's pubic hair trimmer"
Make ya'feel better=Story doesn't matter, but I got kicked in the plums by a guy in Tijauna and he had some kind of a spike or something on his shoe. Bled like hell. Left Mexico never to return. (1958). But this one--my mind is thinking -OUCH while I'm typing= Playing b-ball in the park across from my house. About 10 years old. B-ball backboard and ring was hung on a 4 by 4 wooden post. Ball got stuck, I climbed up to get it, slid down the post and got a splinter about 8 inches long through the skin of my plum sack!! In one spot and out the other. Had to limp home and my aunt had to extract it! OK--------feel better now??
This is one of those threads I don't expect to see grow in page numbers, then when it does I have to see what's going on.
So when you're 80 and reflecting back on your life, you'll recall that you spent the waning hours of 2018 looking at bloody ball sack.
