When I was 19 I jumped over our dog because I thought it was funny how she freaked out, and in trying to not land on her and just get my footing I landed kind of sideways with my leg kind of twisted. Long story short, I broke my hip, but no one, not even I, believed it was a serious bone break until I went to the hospital two and a half days later and they x-rayed it to make sure. They put it back together with three screws. Sitting in certain positions, especially for a long time, can make it hurt (which is really bad for me because I like sitting in a lot of different positions), once in a great while it hurts for no apparent reason, and if I bend my hip and knee more than a little bit, when I extend my leg back to almost being straight it acts kind of clunky and slightly stubborn, like an old car door.
