I always thought that never having to feel any pain would be a fantastic ability; however, it turns out that not feeling any pain actually leads to having quite a miserable life.
It first became apparent to my parents that something was wrong when I was four or five months old.
I began chewing on my tongue while teething. They took me to a paediatrician where I underwent a series of tests.
At first they put a cigarette lighter underneath my foot and waited for my skin to blister. Once they saw that I had no response to that then they began running needles up and down my spine. And since I had no response to either of those tests they came to the conclusion that I had what I have - congenital analgesia.
By which point, I had chewed off about a quarter of my tongue through teething.
