How might you heal a sprained ankle fast?

You can't: I think i've answered this before but, you can't heal an injury. You can only slow healing but doing the wrong things. Rest, ice, compression and elevate are key to any injury. If there is bruising and swelling, get it checked. You may also have a fracture. And don't go to the er. It's very expensive and their priority is life-threatening conditions. I've seen numerous ankle fractures missed.

Ankle sprain: To heal a sprained ankle, it depends on the severity of the sprain. If its a chronically sprained ankle with constant pain and instability, it will take longer than a mild outside sprain. Usually 3-4 weeks of rest, icing, antiinflammatory meds (like advil (ibuprofen) or motrin), bracing or compressing wraps, with or without physical therapy should the starting treatment. Hope that helped!
