I've had two kidney stones in my past. First one was in '97; the last one was in 2000 and it was so bad that I blacked out under the pain, scaring the living daylights out of my then-pregnant xW. They rushed me to the ER. The most pain I've ever had to try to endure. (Afterwhich I finally got a clue and began drinking water with religious frequency!)
Hang in there, lady. If you can work it out of your system, that would be ideal. The second one I had to go through lithotripsy.
