So. Tuesday I was woken from sleep by my phone ringing. Not such an issue, if one has two good legs. But I don't right now and I lost my balance and ended up putting all my weight on my bad leg. It hurt, but only the ankle joint, not any part I associate with the fibula. Then I overbalanced at work the next day and did the same thing. Today, someone strongly suggested I talk to my ortho about it.
The ortho said 'come in now for xrays.'. So I did.

Good news, I didn't damage anything.

Bad news, that pain in my ankle is expected (from lack of exercise) and will be part of what I will be fighting against when I get the boot/walking cast. Also, I can expect to be in the boot for 4-6 *more* weeks. And will still be using the damn crutches for at least two of those weeks. More, I am sure, if I can't strengthen up the leg fast enough.

Take-home message: Don't break your leg.
