Having broken a bone in my foot on the way to the pub many years back (my mates carried me the rest of the way) I think I'd hobbled up to the bar to purchase my 6th pint of Tennants Extra (in the bad old days in Camberley when you couldn't get anything more drinkable) when I bumped into an old sea dog of a Naval medic.
He asked me why I was limping and then provided me with some valuable information on diagnosis of such conditions: If you're on the 6th pint and it still hurts - it's not "just a sprain".
On his advice I spent the remainder of the evening in Frimley Park explaining umpteen times that it was indeed on the way
to the pub and my current state of inebriation had nothing whatsoever to do with my injury.
It didn't half smart, though, for a good few weeks. I don't think my foot has ever been the same since and it was only a poxy little insignificant-looking bone that broke.
