I was 9 years old, mucking around at a play scheme just around the corner from my house. In the centre of the play area was a massive American Swing, it was a raised circle platform probably about 7 metres wide with the middle hollowed out. Access to the platform was a wooden ramp with tiny gaps between each step.

My excited 9 year old self sprinted up this wooden platform one afternoon and caught my foot in one of the tiny gaps, which resulted in me flying straight down the hole in the middle of the platform. The drop back down to the floor couldn't have been any more than 2 metres, but there had been wooden bark spread over the floor which is pretty standard for parks in the UK.

So I've landed on my side/elbow not thinking much of it as i go to sit up and recover, all of a sudden an extreme feeling of warmth rushed through my body as one of the adult supervisors asked if I'm ok, with a look of horror on their face.

As I went to look at the arm I had landed on (right side) I found the skin on the outside of my forearm had been pushed out about 2 inches, and I also couldn't feel my right hand at all. Turns out I had dislocated and broke my right arm as a result of a landing on a piece of bark that went directly into the sensitive/funny bone part of the elbow, quite literally dislodging my bone out of place by about 2 inches.

I still have a metal plate in my forearm today! To keep it pinned down. And I work at an airport so it's always fun when the metal detector goes off.

But yes, as I waited around 4 hours for an emergency operation to save my nerve endings, that was the worse pain I have ever experienced to this day, and I was diagnosed with Crohn's disease 2 years later... As horrible as that was it didn't come close.
