Oh god the pain!

[Martyr]

I had these sour candies that, I suppose, I was supposed to eat sparingly. Like, one a day or something.

However, they were chewy and tasty and I just munched an entire pack of them while I was typing a paper one night.

The more I ate, the more my tongue began to sting, but you know me (don't you). I decided that I was no sissy and pounded all of them.

Coincidentally, I had a very wierd, stinging, sour-type pain in my tongue for nearly two weeks afterward. I must have shocked every taste bud on my tongue to utter agony.

I had this when I was younger, and it made any prolonged exercise unbearably painful. And if I ever fell on my knee, the pain was akin to being hit in the crotch with a sledgehammer. Totally incapacitated

Oh my smurfing god, I had that when I was younger too. It was horrible. And there was really no treatment for it (or at least, none that they gave me), so I spent much of my adolescence growing out of it.

The sledgehammer-to-crotch analogy is rather accurate too.
