I've been in 4 of those camcast things and had my ankle reconstucted twice. I'm happy I can walk without an ankle brace and boots the rest of my life because thats how they told me things would be before they learned about the second surgery I had.

Take care of your ankles. Don't walk on it when you can avoid it. Crutches are a great way to build up upper body strength. Do everything your doctor says so it doesnt get worse. You're lucky you don't have to wear that cast thing in the summer. It can get really itchy. I hope you feel better soon! This is the best time to smoke up.
