I sprained my ankle today. It's swollen and a bit blue, but it doesnt hurt. When will I be able to 'walk' again?

No exact time. Very common question and it varies person to person. Likely soon since not feeling pain. !st start by writing the alphabet letters with your great toe -- moving the ankle in all directions - if can do without discomfort - then try standing and bearing weight on your foot. If that does not cause discomfort - then try walking.
