Whiplash is a neck injury due to forceful, rapid back-and-forth movement of the neck, like the cracking of a whip.
Whiplash is commonly caused by rear-end car crashes. But whiplash also can result from sports accidents, physical abuse and other types of traumas, such as a fall. Whiplash may be called a neck sprain or strain, but these terms also include other types of neck injuries.
Most people with whiplash get better within a few weeks by following a treatment plan that includes pain medicine and exercise. However, some people have long-lasting neck pain and other complications.
