Ouch, that smarts.
I was sitting on the elevated side. When my hand got smashed, I was fairly sure I had broken a finger. Once I got back to base I had it checked at the hospital and, yup, a small crack. Nothing terribly wrong, but I'm going to be a bit inconvenienced for a couple of weeks.
Of course, my colleagues have been every bit as funny about this as I expected... "sounds like someone needs a hug", or, "Hey, did you break your finger throwing yourself out of the back?"
So I will post more when this starts to get better. You should see me typing with the tip of just one finger on the hurt hand... I confess it does look fairly funny.
