Is my big toe sprained?

Today at the skatepark i fell, and somehow hurt my toe. Im not sure if its sprained or not. I can walk on it, stand on my tippy toes, and i was still able to skate for the rest of the day! But its pretty swollen, and even though i can walk i hurts quite a bit. So do you think its sprained? What are some things i could do to heal it faster? Thanks for the help!
