How long will it take for my finger swelling to go down?

On May 4th, I got my finger stuck in a door, and it created a lac on my middle finger just below the finger nail. The laceration also exposed the bone. It healed up fine and both fingernails came fall off and there are new fingernails growing back. The only concern I have is that the laceration site, is now inflamed, and has been every since the dead skin fell off after the stitches were displaced. It’s been about 2 months since this inflammation has been present. I am 100% sure it is not infected, as I visited my doctor and he stated it was fine, although I did not ask about the inflammation. Is this a permanent immflamtion? How long will it be before it’s not sensitive to moderate hits to the finger?

Thanks,
Adam
