I have had stones located in different areas (kidney, ureter, bladder) so my pain has depended on where the stone was and also the size. For example, my worst pain has been from large stones in the kidney that were too big to pass out of the kidney but were trying to. This pain was severe and radiated from the flank down and was accompanied by nausea, sweating, etc. These stones had to be broken up via lithotripsy. My smaller stones passing through the ureter into the bladder have also been very painful with pain still in the flank but lower. My most recent stone I was able to pass and I could literally feel it pass down into the bladder - with some very sharp pain. Once it was in the bladder I was pain free and it was small enough that it was not painful when it passed out of the urethra (I am female if that makes any difference
) So my pain has varied quite a bit based on the size and location of the stones. Please feel free to ask any questions - I have a lot of experience in this area! HTH!
