Here's my lovely list of unpleasantries...
At the age of 7, I tripped real bad down a hill from jump-roping down it (got my foot caught on a rock); hit my head on the cement and the wound started to bleed horribly. I was with a neighbor and her kids, and she immediately had one of them give over their t-shirt (it was summer) and wetted it in a fountain. Applying the wet shirt to my head, we walked home to go deal with it. Some guy stopped his car when he spotted us and asked if I was a gunshot victim! Had no idea how bad it was, until I got home and saw in the mirror that I had blood on me from my head all the way down to my legs. Oddly enough, it didn't hurt and had been bleeding like that from a piece of gravel getting stuck in the wound. Yuck.
Got hit by a car while riding a bike when I was 12 (the street was totally clear, dammit!). I was just a bit aways from the sidewalk when this old guy in a minivan came whizzing down the street, smacked into the front tire of my bike, and sent me flying back onto the sidewalk. OH MUTHAFU--- it really hurt. No real damage (except to my bike, sadly), but it made my hips feel really weird for a week (kinda worries me). At least the guy got out of his car right away to ask me if I was allright, and apologized.
A week after Christmas that same year, I got chicken pox... what a nasty nightmarish time that was. X_X
At age 13, a cat bit me in the skin between my thumb and forefinger, so I had to take antibiotics for it (my dumbass neighbor was abusing her cat, and I'd been taking care of it on my backporch; I was cuddling her cat in my arms when she'd showed up and the cat seriously freaked out... hence why I got bit).
2005 - Fell off sideways off the edge of a sidewalk while rollerblading, and slammed the right side of my ribs really hard onto the curb. GAH... that hurt seriously worse than that bike accident. The pain lingered for several months (esp. if I bumped my side), and I think it meant that my ribs had been bruised.
2006 - Got the Flu big time, with a high fever. I was hallucinating, and when my mom came to help me out, I freaked out kind of like someone on a very bad drug trip. Glad I don't remember any of it. (though that's rather awful; that means some of my brain cells died that day... ugh...)
Scars: Have one below the left side of my lower lip, which looks like a capital L lying on its back; this was acquired when I was 2 years old and jumped off a chair at my grandma's house - bit completely through my lip. Got a big long one on the back of my left hand - played too rough with my cat that day. Have a little claw-shaped one on my right thumb, from being stupid while opening a can of soup (the lid slipped and sliced into my hand; gross and bloody). And I have one big one shaped kind of like a dragon claw, on my right wrist... this was acquired from spilling a pot of boiling water on the front of myself by accident (I tripped while transferring it to another burner; oddly, I have no scar from that), and putting my wrist on the red-hot burner in a stupid instinctive reaction to keep myself from falling.
Gastro-enteritis: The stomach flu FROM HELL. Which I've been unfortunate to have had more than once. Defintely something I wouldn't wish on my worst enemy (well, maybe...heh heh). Makes you throw up AND go diarrhea, and one time I had it so bad that I crapped all over myself at the same time when I had to barf... I was so freaked out and embarassed that I was literally crying in misery. T_T
