Whiplash (Neck Sprain from Sudden Movement)

Whiplash is a sprain of the neck's muscles and ligaments, caused by a sudden jerk such as a road accident. It can be very sore, but it's not usually serious. Most people recover within a few weeks, and surgery is essentially never needed.

What is whiplash?

Whiplash is a neck injury that happens when the head is thrown forward and then backward, or the other way round. It's most often caused by a car accident, especially a rear-end collision, or by contact sports or a fall. Doctors may also call it a neck sprain or neck strain, or a whiplash-associated disorder. The sudden movement stretches the muscles, ligaments and joints of the neck.

What gets injured, and who gets it?

Anyone can get it, at any age, and it's common after road accidents.

• The muscles and ligaments that support the neck
• The facet joints between the neck bones
• Occasionally, the discs of the neck

How serious is it?

For most people, whiplash is painful but not dangerous. Serious injury to the spinal cord or the bones is uncommon in typical whiplash. After a high-speed accident, though, we make sure nothing more serious has happened.

What are the symptoms?

• Neck pain and stiffness
• Muscle tightness or spasm
• Difficulty turning or moving the neck
• Headache, often starting at the base of the skull
• Shoulder or upper back pain
• Dizziness in some people

Symptoms often don't show up straight away. They can build over the next 24 hours, so don't be alarmed if the pain is worse the day after an accident. Get it checked promptly if you have numbness, tingling or weakness in the arms or legs, a severe headache, dizziness that doesn't settle, or pain that isn't improving after a few weeks.

How is it diagnosed?

Whiplash is usually diagnosed from the story of the injury and an examination. Scans (X-ray, CT or MRI) are kept for severe pain, symptoms in the arms or legs, or a high-risk accident, to rule out a fracture or a more serious injury. A normal X-ray is common in whiplash, because it's mainly a soft-tissue injury.

Will whiplash get better on its own?

Yes, for most people. Most recover within 2 to 3 weeks with simple measures. A minority have symptoms that last for months, especially after a more significant injury.

What non-surgical treatments are available?

• Staying gently active: Older advice was to rest the neck. Keeping it moving usually leads to faster recovery
• Pain relief: Anti-inflammatory tablets, and ice or heat, help in the first few days. A short course of oral steroids is occasionally used for severe nerve-related pain
• Physiotherapy: Targeted exercises and stretches restore movement and strength. See Neck Exercises for Pain Relief & Prevention
• A soft collar: Only for comfort, and for no more than a few hours at a time. Wearing one for long and resting too much weaken the neck muscles and slow recovery

When is surgery needed?

Almost never for whiplash itself. It's only considered if a scan finds a significant disc injury or an unstable neck after the accident, or if arm symptoms persist. If you've been told you need surgery after a whiplash injury and you're unsure, you're welcome to send your MRI for a second opinion.

What does surgery involve?

If a disc injury from the accident is causing lasting arm symptoms, the treatment is the same as for other neck disc problems, usually an anterior cervical discectomy and fusion. See Cervical Disc Herniation.

What is recovery like?

Most people are back to normal activities in 2 to 3 weeks. If pain isn't improving as you'd expect, a spine specialist can check for an underlying disc or joint injury, so it's worth having it looked at.

Can it be prevented?

You can lower the risk. Wear your seat belt, and adjust the head restraint so it sits level with the back of your head, close to it. Good neck strength helps too. In contact sports, train and play with good technique.

Questions to ask your doctor

• Do I need a scan, or is this a simple sprain?
• Could there be a disc or joint injury?
• Which exercises should I start with, and when?
• How long before I can drive, work and exercise?
• What symptoms mean I should come back sooner?
