A broken knuckle would be swollen in the area of the knuckle. It can be hard to tell if it is broken. It may just have a fracture.
They will usually heal on their own. Applying ice to the area right after the injury can help the swelling.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
