I fractured my first metatarsle a month or so ago and i have a cast up to my thigh. A week ago, I broke my knee-cap in my other leg. I am now in a wheel chair but the doctor says he does not want to cast my other leg while I still have this cast on. What do you think I should do? Because my knee cap is not heeling and it hurts alot. Do you think I should get a cast put on my other knee?
