i don't know about you, but i'm not a "going to a docter" type of person.

if you are you should go

if you aint, then i would just give it some rest a few weaks.
unless it aint in possition anymore, cuz then it will grow f*cked up.

had kinda the same thing with my middle knukle, and i could feel something was lose, and now i dont have any problems with it anymore.
