Whiplash is a common neck injury that often occurs during rear-end automobile collisions, when your head suddenly moves backward and then forward — similar to the motion of someone cracking a whip. These extreme motions push your neck muscles and ligaments beyond their normal range of motion.

Whiplash injuries can be mild or severe. Treatment typically begins with over-the-counter pain relievers and ice applied to the painful neck muscles. If pain persists, prescription medications and physical therapy may be helpful.

Most people recover quickly from whiplash — usually within four to six weeks — but some people with whiplash injuries develop chronic symptoms that can be extremely painful and disabling.
