What could be wrong with my ring finger?

On Sunday, I slammed it in the pantry door. It hurt really bad, and was red. I put a bag of frozen vegetables on it, and I rinsed it with hot and cold water. Today it doesn't hurt but it moves strangely, and my pinky and middle finger surrounding it is tingling. I'm not sure what to do, I've damaged the nerves in both pinkies on my hands before, and I did the buddy wrap.
