RICE
rest, Ice, Compression and elevation are all important.
Are you sitting with the ankle above the knee to allow drainage?
Be careful how long you ice it for - only a few mins before tissue damage due to cold can set in.
If you run and it hurts, stop. Have you got it strapped?
Sometimes you can save time later by resting an injury when it occurs.
Are you doing any exercises to bring back full mobility, eg supporting the knee and slowly rotating the ankle? Consider a wobble board if you have access.
Best of luck. If you are sensible, the half is a long way away. 2 weeks is a long time in injury land.
