<human>: Condense the text into a few key points

Back Story-

So it was the last month I was on vacation and i find out that my uncle woke up at 5 am and was screaming and crying and didn't know what was wrong. He went to the hospital and they said he had a kidney stone. He was in unbelievable pain and had to go back to the hospital every couple hours to get a shot that would stop the pain. He was in terrible condition for a good 5 days.

Well fast forward a couple of day later and he is in the hospital and the doctors come back with some test results and such and say that the kidney stone just disappeared. Now my uncle was in even worse shape than before. He would sweat buckets and then he would be freezing. This went on for about 5 months. He was in the hospital the whole time too. He would get a tiny bit better every day. The doctors never figured out what was wrong which left everyone dumbfounded.
