Injury.
I seem to have injured my wrist sometime at work today, though I have no idea how. It's fine as long as I hold it straight, but if I curl my hand into a fist and roll it towards my forearm, then it hurts. The pain comes along the back of my wrist, in line with my pinky and ring finger.
Luckily I can still type without any pain, or I'd really be annoyed, but I'm a bit concerned in that I didn't do anything that I know of to injure it.
