I use to sprain my ankles all the time in highschool. don't really anymore but, I'm also not playing a sport full time 3 times a year. The worst I've done is break my ankle in basketball and break my hand. Unless you count concussions in football

Oh yeah! when I was in jr high I had to stop playing baseball and have steroids in my elbow. Apparently when I throw I hyper extend my elbow and it tear bone shards off in my joint. so I wasn't able to pay baseball after that.
