Pinky finger

Hey MP, it's been almost two weeks since something happened to my pinky and it's still a bit swollen. It's not overly painful to make a fist, really hardly no pain just feels a bit wierd. What is happening is it almost feels like it gets stuck and when I press on the red circle in the below pic I can feel it snap and adjust. The snap happens mainly in the PIP joint but mainly on the top/side of the nuckle. This happens sometimes when I straighten my finger as well. At first I was just taking to my ring finger but have now been splinting it for the last two days.
Anyone have anything similar or any ideas?

For the injury, there wasn't a specific move I could remember, but when I finished climbing the route it definitely felt a bit wonky, almost down the side of the hand. The route itself was a bit crimpy and had some dynamic moves "falling" into side pulls and crimps.
