I have had at least a dozen of them.
I have found a few interesting things about them. First, the SouthEast U.S. is the kidney stone belt but they still do not know exactly wy.
The last one I had, they did the MRI and the doctor said I had one in my left kidney which was so large it will not move. The ones hurting and they kept doing so for 9 days, were three tiny ones, about the size of a grain of sand each.
The only really large one I have had actually did not hurt as much as some of the smaller ones. It did pass into my bladder and kept irritating me for over a month before I fianlly passed it. It did not hurt at all when I passed it but I did notice it. I actually saw it hit the grass as I was urinating outside in a pasture.
I picked it up and later washed it (and my hands) off carefully and looked it over. It was about the size and shape of the fingernail of my pinky. It had one side which was very jagged while the other was smooth and had several tiny BB like impressions which I assume came from the kidney.
When a really bad one hits you, you will double over then fairly soon throw up. This keeps happening until it passes, usually within a few hours but like I said, one lasted off and on for 9 days.
The pain medication only helps a little bit when it really hurts.
I have had at least one kidney stone in the past but it passed immediately. The pain only lasted a few seconds before it was over. It was however very pad during it's passing.
A few years ago my wife had a very painful kidney stone experience and was hospitalized because of it. While in the hospital, they gave her an injection of Torodol and she said that the pain immediately stopped. She only had to wait in the hospital for a few hours before passing her kidney stone but once they gave her the Torodol, she suffered no more from the stone.
Unfortunately, Torodol is no longer available in pill form because it causes liver damage. There seems to be no problems injecting it in liquid form though.
Even though I was on Torodol for about four years I was blessed to not have incurred any liver damage. I wish that it was still available in pill form because it was so effective with for me at least no bad side effects.
