Maybe I'm thinknig of something else, but I hear it's easier to sprain your ankle everytime it happens.
[ THE FOLLOWING IS A VERY LONG STORY ]
I had one very serious injury... a spiral fracture of my left femur (thigh bone). A spiral fracture is when your bone twists and then breaks, and considering the thigh bone is the largest and strongest bone in your entire body...
I broke it falling ON a trampoline. No, I did not fall OFF. There was a net surrounding us. I was only 11, so I did not see the danger of someone saying, "Oh hey, let's put these giant balls onto the trampoline so they can bounce around when we jump!" We were all playing the game 'popcorn'. A bunch of people jump around on the outside while someone sits on the inside and gets bounced around.
I was on the outside ring when I landed on top of one of the balls. It shot out from beneath me, and SNAP! I FELT my leg snap. I was instantly in pain and began SCREAMING. Of course, the people who were supposed to be watching us thought I was faking, so they told me either I roll myself off or they do it for me. I was in so much pain I couldn't even remember my own phone number.
I literally at the house for 15 minutes when it had happened. My parents didn't realize exactly how bad my injury was, so instead of calling an ambulance they took me themselves to the closest hospital.
Which is also a hospital with an infamous reputation for incredibly bad service.
I waited for about 6 hours before they took me in for an x-ray, and they tried to force ME to get out of my wheelchair so they can do it. Obviously I couldn't, and by the time they finally took my x-ray they realized that THEY DIDN'T HAVE THE PROPER EQUIPMENT TO TREAT ME. So I get a emergency ambulance ride to the Children's Hospital Of Philadelphia from a great pair of guys. Even though it was their day off, they came in anyway when they found out that a child needed it. :3
After my x-ray, the doctors there are STUNNED. This is how bad my leg is, ladies and gentlemen; my x-ray got into a fucking medical journal. THAT'S how crazy my leg was. But of course, I couldn't go into surgery until the next day, because there just so happened to be 46 (count 'em, 46) other broken legs that same week.
Also, my liver is bruised and my enzymes are FREAKING OUT.
Anyway, the next day I go into surgery for an
external fixator, and I remain in the hospital for 4 more days until I am released. It was honestly the most horrible, traumatic thing that has ever happened to me. I honestly beleived I would never walk again. I had to relearn how to walk, and after the fixator was removed I had to be put in a cast that reached from my chest to the bottom of my foot.
I'm better now, though I'm still terrifed of falling down or injuring myself.
