I Hurt My Ankle The Other Night, Currently Going On

I hurt my ankle the other night, currently going on day three and I believe it is sprained as there is swelling and a little bit of bruising on the outside of my ankle. My question is it normal for my toes to go numb? This only seems to happen when my foot is not elevated. If I just am up on it for a few minutes or even sitting down with my foot down my toes go numb and toes get a little cold. For the first two days I did do the rice, rest, ice, compression and elevation. I currently have on an ankle brace on that is for sprains. I can put a little bit of weight on it but hurts and also hurts to touch my ankle. Unfortunately I do not have insurance so just trying to take care of this on my own.
