Walk it off.
Go to the fruit station...they can glue you another peeling...
I broke my pinky toe two years ago and it HURT LIKE HELL!!! So, if you're experiencing excrutiating pain when you walk, it's likely broken. (Actually, mine was fractured.)
Yeah, I was gonna say, the 70 degree angle relative to the other toes would be your first clue, after the POP.
