Lord have mercy!
I also have heard that kidney stones are awful....I've even heard some women say they'd rather have labor pains. I've never had kidney stones, but I have played nearly an entire rugby game with a broken nose, which hurt worse than when I fell through a few floors of a burning home.
If that's what you're going through...Lord, hear our prayer, and have mercy on the work of Your hands!
Please keep us informed, too!
