I've crashed my bike a couple times out of the thousands of miles I've ridden. Pretty good odds, I'd say. And I got off fairly light injury-wise: Painful road-rash and multi-colored bruises. However, both times I messed up my shoulder something nasty.

I think I had a Type I separation that first crash. Ugh, it took forever for that to heal.
When you crash, don't hesitate to go see your doctor if something isn't working the way it should. Better to go get it checked and find out it's nothing than to wait and make it worse by omission.
Until next time, ride long and keep the rubber-side down.
