I Sprained My Ankle About 4 Weeks Ago. I Fell

I sprained my ankle about 4 weeks ago. I fell down the last step. It swelled immediately and I couldn't put any weight on it. My question is: I still have burning and shooting pain from my ankle to my toes (which even turned black) and so I still can't wear any shoes. I have a very high instep and would rather go barefoot. Is this a good idea? I did have xrays and I didn't break anything.
