Punched a door, not sure of the type of hand injury?

Last night, when I was admittedly intoxicated, I punched a door with my right hand out of frustration. It was a pretty hard punch and left a large hole as the door wasn't of very high quality. I didn't notice any pain until the this morning. It is sore to the touch with a very slight swelling. When I first woke up I couldn't close my hand, but now I can pretty much close it all the way though with some difficulty. The pain is definitely concentrated on the right side of the hand. There is some pain when I move my right index finger or pinky from side to side or when I close my hand or try to pick up something with those fingers having to hold weight. The first two fingers and knuckes are fine. The right side of my hand hurts to touch as well as the pinky knuckle, but only slightly unless I actually squeeze down on it. I can stretch all of my fingers on my right hand to the same height as the ones on the left except for the pinky, which I can't quite raise up to the same height. I can easily touch my thumb to all of my fingers. As far as I can tell I can't feel any bumps or anything that feels broken or out of place. I realize this was a very foolish thing to do.. I lift weights regularly at a pretty high intensity and really really hope that there isn't anything very wrong with my hand. Thank you for any information you could provide about what kind of injury it is and whether or not it's something serious or long lasting.
