I'm dealing with a few injuries at the moment. I woke up one morning with a stiff ankle. The next day it was a sore ankle and for the following few days it spread to being a sore lower leg, aching at night. No idea what caused that - I'm basically in hybernation at the moment. I'd feel better if I'd crashed my bike and had a few scrapes and bruises to show for the soreness, but no such luck.
