Swollen Pinky: Case Closed..Well Sorta

So I had piano lessons today, and I told my teacher about my pinky and how I had no idea what happened to it.  He took one swift look at it and said, "You either have a jammed finger or it's sprained."  Man, I have NO idea WHATSOEVER how he knew that, but now I guess I know what happened to my finger.  It's still a bit swollen and I have no idea what to do to take care of it.  My mom put some minty smelling medicine and a bandaid on it (which I have no idea how the bandaid is supposed to help, but anyways).  I hope the hurting goes away soon.  Wish me luck with my FIRST EVER jammed finger!  Toodles~!

Here is  a picture of my brave, but hurting pinky:
