Are you taking your ankle brace on/off. Depending on the strength of the brace it isn't for long term use. And you should probably be icing off and on a 20min intervals.
Best thing to do when recovering from an injury? Do something that you can hardly even do when it's not freshly injured. Like, I have really serious knee problems. I'm not supposed to do any running, like, at all. Last time I tore the meniscus in my knee? Ran two miles. Why? Just to prove that I could.
This morning I tried to limp up the stairs. My stepdad said I didn't even make a face. (Of course, I was putting as much weight as possible on the handrail and wall on the other side)
