Finger Sport

Whats wrong with my finger?

I jammed my right index finger playing sport 3 weeks ago, tried to catch a ball and the finger was bent backwards too far. It swelled up and hurt like shit for a few days. It's not been 3 weeks, it is still bigger then my left index finger, and is still swollen a tiny bit. When I bend it fully it hurts still. It's been 3 weeks, why hasn't it healed yet? Please tell me.

It is sprained. The ligaments and tendons need to be stretched. You have to do exercises on it regularly, just like you would a sprained ankle. It will take 6 to 8 weeks to heal, longer if you avoid using it.
