Jammed my pinky at bball practice 3 weeks ago, how long to heal?

Pretty self explanitory, I jammed it going up for a rebound and it swelled up a little, not a whole lot but enough to be noticeable. For a few days it hurt really bad but I know it wasn't broken, I could bend it and it only hurt when I touched the joint closest to my fingernail. Its been about 3 weeks and the pain has started to subside a little, now it only hurts when I touch something hard or touch the top or bottom of the joint. However the pain isnt just a sharp sting anymore like it was, its sorta a dull pain that lasts longer. How long should it take to heal, is 3 weeks too long, should it be healed by now?
