I've had two kidney stones.. well, 3 really. Presumably, my second was so big that it broke into two parts and the next bit came out a few days later. That or I just had two at a time -- absolutely brutal, I was lying in the tub just absolutely in the worst pain in the world for about 7 or 8 hours (from around midnight to 7 AM) the night before I passed the first part on the second go-round. The other part came a few days later and was mostly pain free other than when it actually passed.
My first one was when I was only 20 and it was pretty miserable but not nearly as bad as the second one I had about 2 years ago.
