I broke my Distal Fibula and Tibia in a car accident a few years ago. I was "lucky" that I broke my left arm at the same time, so I didn't have to use crutches. I used a rockin cane.
Your leg/foot will itch. DO NOT STICK ANYTHING DOWN THERE! My dad broke his leg years ago, used a wire hanger to itch it and cut himself up pretty badly. The itching will go away. Just grit your teeth and deal with it. When you get that cast off, your foot will stink pretty badly. And you'll have a forest growing on your legs.
If you can, see about getting a walking cast. You probably will towards the end of your cast days.
Just take it easy though. If you have people around, this is the perfect excuse to be waited on hand and foot
Take it easy, heal up, and feel better soon
