I have a 15 yr. history with kidney stones. 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. However, these very slight spasms have continued off and on since that attack 3 weeks ago, but this last week they are progressively getting worse, more painful, and more constant. Sometimes I feel something that seems to be very sharp and it feels as though it's right at the end of my urethra. I took a urine specimen into my family doctor a couple days ago and they felt it was cloudy therefore sending it out for analysis, but also put me on cipro. If it's an infection, it's not helping. Could it be another stone stuck? I only call my urologist as a last option, but think it's time.
