Funnybone Injuries

I'm guessing some of you have probably whacked your funnybone on something, and you know the results. If you don't know what your funnybone is, its an area on your arm right below your elbow.
If you've never hurt it, you're probably wondering why this is differant than any other injury. It happens to be that the funnybone is sensitive in a weird way. When you hit your funnybone on something, it litterally feels like your whole arm is on fire. It gets hot, tingly, and hurts...a lot.

A few days ago, I banged my funnybone against the corner of a wall when I was walking around it. I don't remember exactly how I banged it, but I can remember for sure that it was dumb. It's funny how the pain spreads out. It goes on your whole lower arm, the center of your palm, and it hurts the most of anywhere on the outside side of your palm; even though you banged halfway up your arm. If I hadn't hit my funnybone, the bang would have been a mere scratch.

I'm wondering. Why? Why your funnybone? Why that spot? Why even at all, does that place have to erupt in pain?

Anyway, due to numerous funnybone injuries, I've found out that immediatly soaking your arm in water under a sink helps the pain.
