i wrote this long post yesterday afternoon, saved it as draft, and now don't feel like publishing it. sorry.
the long and short is that i'm waiting to find out if i broke my foot... ten days ago. i've been walking around trying to ignore it ever since. apparently that's not a good way to treat a broken foot, if indeed it's broken. it's probably just a bad sprain. but either way, i would not recommend the walk-around-on-it form of treatment.
