assistant
Causes of a sprained ankle include twisting your foot or ankle, tripping or falling onto an outstretched foot, or landing on uneven ground. Symptoms can range from mild pain and swelling to severe pain that makes it difficult to walk or put weight on the injured ankle. Other signs may include tenderness, bruising, limited range of motion, and difficulty bearing weight. If you suspect a sprained ankle, seek medical attention as soon as possible.
