A sprain is an injury to the tough ropey fibers (ligaments) that

sensation, such as numbness or tingling, may be present.
Treatment for a sprain includes rest (immobilization), ice,

treatment with a cast or splint, physical therapy, medicine, or surgery.
Recovery time for a sprain varies depending on a person's age and health and
the location and severity of the sprain.
