Only a few, but I've hurt myself a lot, actually.
I've really only broken a few fingers, and jammed some. Most of the time, it included a ball and finger collision, but it was never really bad. Though, my pinky healed at a somewhat weird angle...
I dislocated my kneecap a few times. First from running, which healed fine. Then from falling onto the gym floor on my knees. I had to wear a brace for a while.
Also, almost broke my tailbone from slipping on ice last Winter.
And I've sprained my ankle a few times. Nothing serious.
My friend has hurt herself a lot more than I have. She has a problem with her shoulder, almost broke her arm this last weekend, broken fingers and toes, broken her foot [barely] for an incredibly stupid reason, and I can't count how many times she's been in a sling or on crutches. We joke about her being accident prone all the time.
