I think when I was 7, I twisted or sprained my ankle playing mini-golf

I also have a couple jammed knuckles from jr. high football I still feel effects from

When I was a sophomore in high school, I was pitching in a softball game and took a line drive to my shin, if I wouldn't have jumped first, it would have hit my knee...so no lasting damage there, it bruised, and the stitch marks of the ball could easily be seen on my shin.

That same year, I somehow managed to get an inguinal hernia, but I'm not sure if that was a direct result of sports though...I didn't figure out what it was for a long time, and didn't deal with it until I was in my early 20s...so glad it's gone now, plus I have a nice scar by my junk.
