Hi I cut the knuckle of one of my fingers with a kitchen knife about 3 weeks ago. The skin sealed nicely with the exception of a small bump (I'm guessing scar tissue) I hada bandaide for about 2 weeks and finally took it off. I find it a b it stiff now when I try to completely bend my finger to a closed fist. I cant tell if its the tenderness that's stopping me from trying to close it all the way... When I close it slowly it almost does Bend closed all the way but afraid to do it quickly. Should I be worried about tendons? could I have cut my tendon off? My fingers is aligned perfectly like the others! Could it just be soreness from the wound and that more healing needs to take place?
