Is there an awesome person that can answer my question?

Hello.

I'm writing a story right now and I'm a little bit stuck. My question is what would be considered a good amount of time to recover from a badly sprained ankle?

My character is a dancer who just got done recovering from a threatening sprained ankle and is getting back to what she does best....ballet. So I want to say an amount of time but I also want it to make sense to someone who is reading it that would know the answer to this question.

Can someone please help me out by answering this for my story?
