What Is The Treatment For Ankle Fracture?

I am going into the fourth week of a broken ankle. Broke tibia and fibula = 8 screws and a plate. Doing well so far. I have a boot which I can remove. How much movement should I be doing for my ankle - up and down etc...just didn't want to loosen anything. It is a little tight but I can wiggle toes and move my foot up and down. thank you
