Whiplash is an injury caused when the head whips forward and backward very quickly. The sudden movement causes strain on the neck and shoulders, and it can cause headaches, dizziness, and other side effects.
Whiplash is not as serious as some injuries, and typically it is not life threatening. That doesn't mean it won't affect your life, though. When a whiplash injury takes place, it can be completely devastating. It can lead to permanent disabilities of the neck and spine in some serious cases.
