I have apparently passed a kidney stone this morning (from my kidney to my bowel) and OMFG it hurt a lot.
Worse than the disc prolapse.
I have been to the doctors and they could see that the scan I had last year had found the stone, but my assumption that they would call me if there was a problem was apparently an incorrect one. I understand that they are able to "zap" the stones with some electromagnetic pulses to break them up which could have avoided this mornings pain.
I don't really mind that, it has stopped hurting now so life may continue. I just hope that it's the end of it and that there aren't more to come.
