Could I have fractured my toe?

I took the bus home from school on Tuesday...the bus lurched and I fell, scraping my left knee and stubbing my big toe on my left foot. Now my toe is swollen and it really hurts to move it up or down. (There is only slight up and down movement of this toe). I can't bend/curl my toe either, and I'm limping because I have to keep the toe straight when I walk as it won't bend. Is it possible that I've fractured my toe?
