Whiplash is a neck injury due to forceful, rapid back-and-forth movement of the neck, like the cracking of a whip. Whiplash most often occurs during a rear-end auto accident, but the injury can also result from a sports accident, physical abuse or other trauma.
Common signs and symptoms of whiplash include neck pain, stiffness and headaches. Most people with whiplash recover within a few months after a course of pain medication, exercise and other treatments. Some people experience chronic neck pain and other ongoing complications.
Whiplash may be called a neck sprain or strain, but these terms also include other types of neck injuries.
