I hurt my pinky toe last night.?

i was running away from my friend who was chasing me and i guess i stubbed it or bent it back on the corner of a room.. I know its not broken because its not swollen or blue or anything like that. but it hurts to step on it. I have a dance show to do in about 4 hours. I cant quit it. what do i do to make it feel better? so i can dance.
