I can't find the thread, and I didn't bookmark it, but here's the long of it.
The sidewalks out front of my house were icy, I had one foot on dry concrete, and one foot on ice when I slipped. I started to do a forward split when my brain kicked in and thought "I'm not that flexible, doing the split is going to hurt like the ************** and so it decided to autocorrect my front leg. To do that, my hip kinda rotated out in order to bring my foot back underneath my leg. My heel swung around in a semicircle, coming to rest directly underneath my crotch. I landed balls first onto the heel of my boot and racked myself like I've never racked myself before. Somewhere around 200lbs of weight, in a freefall, came crashing down on my nads. For the next week or so, it felt like someone was gripping my nuts just hard enough to keep me on the verge of vomiting my brains out.
I basically tore something, or bruised it, or scraped it hard enough to give myself
epididymitis.
