I sprained/rolled my ankle yesterday, should i dance today?

So yesterday in gym i was running and my ankle totally gave out on me and rolled and i felt A LOT of pain. Plus, it was in gravel so i have a pretty bad scrape on my knee, that hurts when I kneel. Today i have to do a dance show .. im not sure if i should do it. i tried practicing but its hard to tell when im doing it in my tiny living room. im afraid if i dance, im going to injure it even more, and i DONT want that .
