Ankle

So I wrote last week that I rolled my ankle and I thought it was fine.  I even did two mediocre runs on Thursday and Saturday but it seemed to be going well.  Last night, when we were having dinner outside, I took off my socks only to see my ankle had swollen up!  I am so bummed as I really need to train for the next 5K in 2 weeks.  I'm not sure what I can do.  I guess I need to just rest and hopefully it will get better by next week so I can get a few training runs in before the race.
