I sprained my ankle 6 months ago. there's still discoloration on both sides, sore, and now numbness in my foot and toes. ?

Not only a sprain: A sprained ankle is a very vague term for an ankle injury. A sprained ankle can have numerous pathologies. A simple sprain is a slight stretching of a ligament around the ankle joint that should resolve in a few days to a couple of weeks. This was obviously more than that. An ankle sprain can consist of torn ligaments or tendons, broken bones, dislocations, capsule tears, loose bodies, and more.
