Whiplash and neck injury

What whiplash is

Whiplash happens when your head is thrown suddenly in one direction and then snaps back. This strains the muscles, ligaments and joints in your neck. It is sometimes called a neck sprain or strain.

It is most often caused by road traffic accidents, especially being hit from behind. It can also happen after a slip or fall, a sports injury such as rugby or boxing, or a sudden blow to the head.

Anyone can get whiplash. Recovery tends to be slower for people who are older, who had neck pain before, whose pain is severe at the start, or who are very distressed after the accident.

Grades of neck injury

Doctors often grade whiplash injuries using a scale called the Quebec Task Force grades. Most injuries are grade 1 or 2.

Grade 1

Neck pain, stiffness or tenderness, but nothing unusual found when a doctor examines you.

Grade 2

Neck pain with signs in the muscles and joints, such as less movement and tender spots.

Grade 3

Neck pain with signs that nerves are affected, such as numbness, weakness or changed reflexes.

Grade 4

A broken bone or dislocation in the neck. This is a medical emergency.

Chronic whiplash

Pain and other symptoms that last more than 3 months. Doctors sometimes call this whiplash-associated disorder.

Symptoms and recovery

Common symptoms include neck pain and stiffness, finding it hard to move your head, headaches, and pain or muscle spasms in the shoulders and arms. Some people also feel dizzy or tired, find it hard to concentrate, or feel anxious after the accident.

0 to 48 hours

Onset

Symptoms can take several hours, sometimes up to a day or two, to appear. Pain often gets worse over the first 24 to 36 hours.
First few weeks

Early recovery

Pain usually starts to ease within days or weeks. Keeping moving speeds recovery.
2 to 3 months

Most people recover

Most people are better or much better by this point.
More than 3 months

Long-term pain

Some people still have pain and disability. If symptoms last beyond 3 months, they are more likely to continue for a long time.

About half of people recover fully. About 1 in 4 are left with mild problems and about 1 in 4 with moderate to severe pain. (Physiopedia, summarising research)

When to get urgent help

Call 999 if someone

is unresponsive after an accident
has severe neck pain or can't move their head
has numbness, tingling or weakness in their arms or legs after an injury
has fallen from a height, such as 5 or more stairs
has problems with their bladder or bowels after an injury

Don't move someone who may have a neck injury unless they are in danger.

Ask for an urgent GP appointment or call NHS 111 if

your pain is severe and painkillers aren't helping
you have pins and needles or tingling
you have problems walking or standing up straight
you get sudden "electric shock" pains
your arms or legs feel weak

See your GP if

your symptoms haven't improved after 1 week
painkillers like paracetamol or ibuprofen haven't worked
you are worried about your pain
pain is stopping you working or sleeping

Diagnosis and referral

Whiplash is usually diagnosed from what happened and an examination. Most people don't need an X-ray or scan. Scans are used if a doctor is concerned about a broken bone, nerve damage or another injury, for example after a high-speed crash or a fall in an older person.

If your pain isn't settling, your GP can refer you to physiotherapy, a pain specialist or psychological support. In many areas you can refer yourself to NHS community musculoskeletal (MSK) physiotherapy without seeing a GP first.

Treatments and medicines

The most important treatment is to keep your neck moving and carry on with everyday activities as much as you can. It might hurt a little, but it speeds up recovery.

Simple painkillers

From a pharmacy or supermarket

Paracetamol and ibuprofen. They work best taken regularly for the first few days, rather than waiting until the pain is bad. Ibuprofen isn't suitable for everyone, so ask a pharmacist if you're not sure.

Stronger painkillers

Prescription

If simple painkillers don't help, your GP may prescribe something stronger, such as codeine, for a short time. Codeine can cause constipation and drowsiness, and isn't for long-term use.

Gentle exercises

At home, from day one

Gently move your neck in all directions, little and often, along with shoulder shrugs and circles. Stop if an exercise makes you dizzy.

Physiotherapy

NHS by self-referral or GP; or private

If pain isn't improving after a few weeks, a physiotherapist can give you a tailored exercise programme. Research shows early exercise works better than wearing a collar.

Psychological support

NHS talking therapies, often by self-referral

Accidents can be frightening. If you have flashbacks, worry a lot, or are avoiding travel, talking therapies can help. Feeling distressed can also slow physical recovery.

Don't use a neck collar

Soft neck collars and long periods of rest are no longer recommended. They can make your neck stiffer and slow your recovery. Hospitals no longer routinely give collars for whiplash.

If pain lasts

If your neck pain lasts more than 3 months, it is treated as long-term pain. Treatment then focuses on getting back to normal life rather than finding a quick fix.

Exercise-based physiotherapy

Usually several weeks of sessions and home exercises

Strengthening the neck and upper back, improving movement, and gradually building up activity.
Pain management

Referral to an NHS pain clinic or programme

Programmes that combine physical activity with psychological approaches, such as CBT, help people manage long-term pain, sleep and mood.
Other specialist options

Varies

For some people with pain from the small joints of the neck, a pain specialist may suggest injections or nerve treatments. Ask about the evidence, the likely benefit and how long any relief may last.

Self-help and living well

In the first few weeks

Keep doing your normal activities as much as you can
Take painkillers regularly if you need them
Try heat or a cold pack on your neck
Do gentle neck exercises every couple of hours
Sleep on a low, firm pillow

If recovery is slow

Set up your desk so your screen is at eye level
Take regular breaks from screens and driving
Build up activity gradually rather than all at once
Ask for help if you feel anxious, low or are avoiding travel
Check with your doctor before driving if you can't turn your head fully

Tips for getting the best treatment

Before your appointment

Write down when and how the injury happened, and when symptoms started
Keep a diary of your pain, headaches, sleep and what you can and can't do. It is useful for your doctor, your employer and any claim
Ask: "Should I be referred to physiotherapy?" if you aren't improving after a few weeks
Check if you can refer yourself to NHS physiotherapy in your area
Mention any anxiety, flashbacks or poor sleep after the accident
If pain lasts more than 3 months, ask about a pain management programme

If you choose private physiotherapy, check the physio is registered with the Health and Care Professions Council (HCPC). If you are making an insurance claim, ask whether the insurer will pay for rehabilitation.

Whiplash and work

Most people go back to work quickly, and staying in work usually helps recovery. If neck pain becomes long term, it can count as a disability under the Equality Act 2010 (the Disability Discrimination Act in Northern Ireland). This applies if it has a substantial, more than minor, effect on your daily life and has lasted, or is likely to last, at least 12 months.

Even before then, many employers will agree changes. Reasonable adjustments might include:

A monitor arm or riser so your screen is at eye level
An ergonomic chair with head and neck support
A headset instead of holding a phone
A sit-stand desk
Less driving, or breaks on long journeys
A phased return to work
Regular breaks to move
Time off for physio appointments

Access to Work is a government grant that can pay for equipment, travel to work and support. See GOV.UK on reasonable adjustments, or contact Acas or Citizens Advice for advice on your rights.

Benefits and claims

If you can't work for a while, you may get Statutory Sick Pay from your employer for up to 28 weeks. If long-term pain affects daily tasks or getting around, you may be able to get Personal Independence Payment (Adult Disability Payment in Scotland). New Style ESA or Universal Credit may help if you can't work.

If you were injured in a road accident in England or Wales that wasn't your fault, and your injury claim is worth less than £5,000, you can use the free Official Injury Claim service without a solicitor. Whiplash payments are set by a fixed tariff based on how long your injury lasts.

How The Beyond Pain Foundation can help

If NHS waits are too long, or the help you need isn't available to you on the NHS or through an insurance claim, we may be able to fund:

A course of private physiotherapy with an HCPC-registered physio
A private pain management programme
A private consultation with a pain specialist
An ergonomic chair, monitor arm, headset or sit-stand desk for work or home
A TENS machine, if your physio or doctor suggests one

We fund treatment, equipment and support, not general living costs. Prices vary, so always get a written quote to include with your application.
