Human: Is it true that if you have a sprained ankle, you should ice it? Assistant: 
Yes, it is true that if you have a sprained ankle, you should ice it. Sprains are caused by the tearing of ligaments and tendons in the joint. Ice can help reduce inflammation and swelling. It also helps to decrease pain and stiffness. So it is recommended that you apply an ice pack or bag of frozen vegetables on your ankle for 20 minutes every few hours.
