I jammed my left index finger while playing basketball about 3 and a half weeks ago. It felt like it popped or cracked, and I was initially concerned that it dislocated, but it wasn't. It immediately swelled up, but I continued to play with it. Later that night, I splinted it, simply thinking it was a jammed finger. It felt better after a few days, but it hasn't really improved at all. There's still a tender spot along the second and third knuckle, and it hurts to fully straighten or bend it.
