Whiplash: symptoms, recovery time and when to get checked
What whiplash is, why symptoms can appear hours after a jolt, what the NHS advises for recovery, and the warning signs that need urgent help.
Whiplash is a neck injury caused by a sudden, forceful movement of the head, most often in a car collision but also in falls and contact sport. The soft tissues of the neck are strained, and symptoms can take several hours, or even a day or two, to appear.
When to get urgent help
Call 999 straight away if neck pain comes with any of these. They can be signs of a stroke, meningitis or another emergency.
- Sudden severe headache unlike any you have had before
- Dizziness with double vision, slurred speech, facial droop, difficulty swallowing or weakness in an arm or leg
- Neck stiffness with a high temperature, severe headache, rash or dislike of bright light
What it can feel like
- Neck pain and stiffness, with difficulty moving the head
- Headaches, often starting at the base of the skull
- Pain and muscle spasm in the shoulders and arms
- Symptoms that may take several hours to come on after the injury
Common contributors
- Car collisions, particularly being hit from behind
- Falls, sporting collisions and tackles
- Any sudden jolt that throws the head forwards then backwards
- Recovery can be affected by stress, sleep and worry about the injury, as well as the physical strain itself
General self-care
These are general comfort measures many people find reasonable. They are not a treatment plan, and what suits one person may not suit another.
- Keep doing everyday activities. The NHS says this may hurt a little but speeds recovery
- Do not rest your neck for long periods, and do not wear a neck brace or collar, as the NHS says they do not help
- Take painkillers such as paracetamol or ibuprofen if you need to. Follow the packet instructions
- Gentle neck movements within comfort, built up gradually
- Do not drive or cycle until you have spoken to a GP or NHS 111 if you have any of the warning signs below
When to see your GP
See your GP promptly, or call NHS 111, if you have any of the following:
- Neck pain after a significant fall, accident or blow
- Numbness, tingling or weakness spreading into the arms or hands
- Unexplained weight loss or a history of cancer with new neck pain
Consider seeing your GP if:
- Your symptoms have not improved after a week
- Painkillers are not working, or you are worried about the pain
- Severe pain, tingling or pins and needles on one or both sides, problems walking or sitting upright, an electric-shock feeling in the neck and back, or weakness in the hands, arms or legs. The NHS advises an urgent GP appointment or NHS 111 for these
Where an osteopath fits in
There is limited good-quality research showing that hands-on treatment changes the course of whiplash, so I do not claim that osteopathy treats it.
The NHS says whiplash usually improves within two to three months, although some people have symptoms for longer, and that keeping active speeds recovery.
What an osteopath can usefully do is carry out a careful assessment first to decide whether further medical checks are needed, then advise on a graded return to normal movement and activity, ease muscle tension and headaches where that is a feature, and help you plan work, driving and exercise around symptoms. If the assessment suggests you need your GP, a physiotherapist or a specialist instead, I will tell you.
If you would like your symptoms assessed, you are welcome to book an appointment. Osteopathic care is not right for everyone, and if something needs medical attention first, I will tell you.
Common questions
How long does whiplash take to heal?
The NHS says whiplash usually improves within two to three months, although some people have symptoms for longer.
When do whiplash symptoms start?
They can take several hours to appear after the injury, and sometimes a day or two. Neck pain that starts later after an accident should still be taken seriously.
