i hurt my toe about two months ago, and i can only bend it half way still. whats wrong with it?

i was chasing my dog and i slipped and fell. i started running and i noticed that my big toe hurt, and it was bent to the right. for the next few weeks, it hurt to touch or walk on. now, it doesn't hurt, but if i try to bend it it only bends half as much as my other big toe. does anyone know what happened to it, and when it should fully heal?
