Expected Duration

How long it takes to heal depends on the severity of the sprain. Grade I sprains usually take one to two weeks to heal completely. Grade II sprains can take up to six weeks. Grade III sprains can take six months or longer to heal completely. On average, count on a two- to four-week healing period for any significant sprain.
