After I had about a year of skating lessons under my belt (group lessons), or maybe it was my first year, I don't remember, I had my birthday party at the rink. I was, ahem, showing off, and doing a spin. Near the boards. I must have lost control, because I have a vague recollection of hitting the boards, but only clearly remember waking up on a bench in the warming room. I was around 6/7 years old. Classy.
I obviously skated many, many times since.
I once saw one of the other girls I skate with fall backwards out of a layback. We were around 12/13??? It was the only time I've ever seen anyone older than 5 cry like that. Thankfully she was OK. She skated many times after, too!
My best injury happened when I was 13. I was running through my program, fell, got up and in the process kicked myself in the wrist. It must have been particularly cold, or I was particularly pumped because I didn't notice it until I finished and saw the blood dripping. I missed the main artery by a few millimeters, and still have the imprint of a 1987 era MK Professional toepick in my wrist. Over time the battle scar has faded, but that first summer every time I went to the pool (i.e. every day) it turned purple. That was awesome.
Oh, and I nearly forgot, last year I was practicing a lift with someone for the gala, and another skater wasn't paying attention and in collision avoidance mode, smacked her hand into my partners blade. Yeah, they can cut!
Skating should probably carry a Surgeon General's Warning....
