Sprain

Tearing or stretching of the ligaments that hold together the bone ends in a joint, caused by a sudden pull. The ankle is the most commonly sprained joint. A sprain causes painful swelling of the joint, which cannot be moved without increasing the pain. There may also be spasm of surrounding muscles. Treatment consists of applying an ice-pack, wrapping the joint in a bandage, resting it in a raised position, and taking analgesic drugs. In severe cases, surgical repair may be necessary.
