I also hate sitting...but as someone who sprains an ankle every 6 months or so (long story, previous injuries etc) the best you can do is stay off of it for at least a day, possibly two. Wrap it up best you can if you are going to move for the next couple days. You just need to stay off of it as much as possible.
