Kidney stones. The first one was bad but it passed while I was in the emergency room. The second one, a year later, was much worse.
For what it's worth, my nurse had 3 kids and kidney stones. She said she would rather give birth than pass another stone.
About 2 weeks ago.
After my back surgery, 1st 2 days were hell, pretty bad for another week after that. Not sure is I'd want to go thru that again. Morphine didn't put a dent in the pain.
