In the summer of 2011 I woke up in the middle of the night experiencing a pain I had never had before. I was quickly transported to the hospital and after a complete checkup I was diagnosed with kidney stones. Ot was a minor occurrence and there was just a tiny 3mm stone looking for its way out.
A couple of days later the journey was over and that was it.
It turns out that riding roller coasters helps people passing their kidney stones. I wish I knew it back then.
