I was a senior in High School(1964), and was getting ready to leave. I noticed my Dad, coming out of his bedroom, in severe pain, in his back and groin.
I took him, to the Hospital and they did all the tests, and determined he had a Kidney stone. They tried flushing it, but it wouldn't come out far enough.
The next day, they set up a camera, and a probe. They gave him needles in his private area, and went fishing up his penis.
After about 45 minutes, the doctor pulled the probe out and the stone was on it. It was a little larger, than a wooden match head. When Dad told me, how they took it out, I almost puked.
After a few days, he came home, and was OK.
Glad your OK, Bryan.
