Walking may be moderately difficult. Recovery time is 4 to 8 weeks. At the time of the injury in a third degree sprain, the joint may slip out of place and then back in. There is massive swelling, severe tenderness, and instability in the joint. Walking may not be possible.
Surgery is sometimes necessary.
Recovery time is 6 to 12 weeks. Severe ankle sprains need medical care. It's a good idea to be evaluated for a possible fracture. Ice the injury as soon as possible. Cover your ankle with a WET towel and place a plastic bag full of ice over it.
