Had em once. Worst pain EVER. Paced the floor all night till the next morning when I could call the nephrologist (kidney doc) across the street. He said the fact that I didn't go to the ER meant it wasn't too bad (NOT BAD?!?!). He said drink a BUNCH of water and you'll pass it. I did. I'm sure I havent been drinking as much water as I should.

20 years earlier a young (late 20's) customer from out of town asked if he could borrow my keys and lay down in the back of my car. I reluctantly said sure. When I went to check on him and hour later I thought he was giving BIRTH. We called an ambulance. This guy used to work for a road construction crew. Said he was holding a tube to place explosives in a hole. Said it exploded and shrapnel caused his arms to swell and the doctors cut the muscles loose before they tore off the tendons. He said that was NOTHING compared to the kidney stones.
