I hurt my ring finger when i fell. it feels dislocated. little inflamation. i can't close or open fully. what do i do to help? could it fractured etc?

Possible: It's certainly possible that you may have sustained a fracture (broken bone) when you fell - x-rays will show this. A dislocation is usually not subtle - in most cases the joint will be obviously out of place. Loss of range of motion is very common after finger injuries - even just sprains. It's very important to restore that range of motion, so see a physician for further evaluation.
