Thank heavens it's only stones, but I know that is still going to be majorily uncomfortable for her.
One morning I woke up about 3am in amazing pain. I paced back and forth, all over the house, drank a whole lot of fluids, released those, went back to sleep for a few hours and went to work. I went to my Dr. and told her I had passed a kidney stone, and she said that was impossible, that it takes weeks and months to pass one. I kept insisting.
A few months later, the same thing happened. I told my Dr. again that I had passed a kidney stone in several hours. This time she believed it. Said I was so adamant the first time that she looked it up, and discovered that some people can pass them in hours. I was very lucky! Hope Lisa gets lucky too!
