The Most Painful Things A Human Can Experience

First off, this video is about physical pain to your body, so heartbreak and psychological distress aren't considered, even though they can be pretty painful. What is the most physically painful thing that might happen to you? Scientists have been trying to figure that one out, and some of the conditions they study will make you cringe. In fact, watching this video may cause a little cognitive pain. 

Many years ago, someone (who had never spent time in a burn ward) told me the most painful things were childbirth, a spinal tap, and a root canal. I asked my mother about that, because she's had all three, and she told me none of them were painful thanks to drugs. The worst pain I can recall was when I was stung in more than a dozen places by wasps. That was only last month. (via Sploid)
