I've had bad kidney stone pain 3 times (once for stones on both sides - laser up my penis for one side, ultrasound for the other) - the only thing that might have been worse for me was one time I hurt my back, which pain dropped me to the ground immediately.

Question: I know that evolution doesn't actually work this way - but what the hell is the reason for pain receptors in the kidneys? Pain is your bodies way of saying "stop doing that" - and what does my hunter-gatherer body think I'm going to do about a kidney stone, beyond writhing on the ground to tell the passing tiger "here's an easy meal"?
