I stub my toes regularly, but once, when I was in the Caucasus, some years ago, en route from the bathroom, minus spectacles, and having just showered, I managed to walk into my (full) suitcase; there were stars dancing in front of my eyes and a feeling of excruciating agony in a small toe.
From experience, I knew this stuff (discomfort, pain, agony) usually passed after around half an hour. That particular day, it didn't.
Two days later, I was still limping, and - upon examination - my toe had gone some strange shade of deep ominous purple bordering on darkest velvet midnight black.
A quick search online made me aware of some things I think I might have preferred not to know.
Now, I was in the country in a senior capacity to observe an election, and the thought of being repatriated home at the start of a deployment due to last a few months on account of a broken toe (I could imagine the howls of laughter of my colleagues) didn't really bear thinking about. Besides, I was to be driven (almost) everywhere in a nice BMW X5.
So, I said nothing, limped a bit until I limped no longer, and observed the election.
