I've been hobbling around now for a whole 24 hours. And feeling mighty sorry for myself.
The good news is the swelling is minimal (just enough to feel uncomfortable), and there's no break. I can get up and down stairs (slowly) and can put my weight on it (carefully). The bad news is I probably won't be able to do yoga for a week at least, and won't be starting the running regimen for at least two weeks.
Which should be enough inactivity to make me grouchy.
