I had my most recent attack 3 weeks ago and it was one of
the longest enduring of
any I've had, with the most severe flank and ureter
pain lasting almost 12 hrs. The last couple hours of the horrible pain, I experienced what I would almost call spasms very low down, and I've never had that before in any of the other attacks. I had waves of pain and the urge to urinate every few minutes. I passed two stones 42 hours later, and I've passed two more in the time that has passed with no pain.
