Swollen pinky toe....?

About 45 minutes go I stubbed my pinky toe in a door frame and now it's swollen and when I move it it would pop. Then, when I tried walking on it the bone that connects the toe to my foot popped up but stayed under my skin and it feels warm and I am able to move it. I just want to know if it's anything serious. And I can still walk on it but it hurts a little.
