Worst injury/injuries you've sustained?

[bdk3clash]

Looking back on my life I've been incredibly lucky in terms of doing lots of stupid stuff and not getting seriously injured. I've really only had two serious injuries, the most recent being about 14 years ago.

When I was five I was playing on the monkey bars and fell and landed awkwardly on my arm, breaking my wrist and having to wear a full-length cast for a few months.

When I was a a freshman in high school I got popped helmet-first on my chin during football practice and got a pretty nasty gash, a concussion, and a crooked chin.

Let's hear about your injuries in all their nasty glory. Mine are pretty pathetic.
