I don't see a lot of my feet in the winter. It is cold and wet and so I wears socks (even to bed) and forgo my summer habit of flip-flops. This meant that I hadn't noticed something very strange has happened to my left foot.
The last two toes (which suffered from total loss of feeling for about the first half of last year) no longer are stretched out but curled permanently under. No wonder my feet hurt!
