What is an ankle sprain and how is it treated?
A sprained ankle is an injury to an ankle ligament. Ankle sprains are graded on a scale from 1 to 3, with Grade 3 being the most severeāa complete tear of the ligaments that stabilize the ankle joint. A Grade 3 ankle sprain can be more painful and take longer to heal than an ankle fracture. Treatment often involves putting the ankle in a cast to protect it while it heals.
