Back Pain
I had a herniated disc in my back a few years ago, and as I'm sure anyone else who had one knows it is incredibly painful and led to somewhat embarrassing situations (such as having to be helped off of the toilet etc).

It doesn't bother me so much any more, but occasionally I feel a twinge in my upper back. Luckily my other half is often there to alleviate the pressure with a swift bearhug, which is probably not very good for my spine in the long term. But I digress.

I used to work in a convenience store with a small outside warehouse which had a little concrete ramp leading back into the store. By the side of the ramp was a railing, about three feet high or so. You can probably see what's coming. During an afternoon I was loading stock onto a trolley when I felt the familiar twinge between the shoulder-blades. I spied the railing and realised that if I braced my hips and bent over it backwards, I could probably snap my back and alleviate the pressure.

So I approached the bar, got into a squat and leaned back. Nothing happened so I leant a bit further. A bit more. Then a bit more, until I was tottering on tiptoe. I was fine until I stupidly flung my head back to get my neck to align with my spine, wherein I arced gracefully over the slippery bar like a pole-vaulter, and with a cry I fell backwards into a heap on top of some wet cardboard boxes.

Miraculously, I had only slipped backwards into the mulch rather than cracking my skull open and the main victim was my backside. I lay there for a few minutes, feeling a bit sorry for my stupid self, before getting up and continuing with my work.

Thankfully nobody saw, but if they had it'd have served me right.
