It is like the Inquisition and the torcher chambers. I have broken bones, had 3 back surgeries including a fusion with all kinds of metal in me. I have wiped out skiing so bad I should be dead. 2 foot surgeries, a shoulder surgery, a wrist surgery. None compare to the pain of stones. Even Viral Meningitis two times. That is close as it feels like your head is going to explode.I had kidney stone surgery also, and waking up with a string coming out my junk, with the doc tell me to take two pills and yank the string out was the worst experience of my life. It's like some weird horror movie with a sadistic doctor.
