Neck Pain and Headaches: The Link Most People Miss

You've probably reached for paracetamol more times than you can count, blaming your headache on screens, stress, or dehydration. But if you press your fingers into the base of your skull or the muscles either side of your upper neck and feel tenderness or a familiar ache spreading upward, there's a good chance your headache didn't start in your head at all. It started in your neck.

This type of headache has a name — cervicogenic headache — and it's one of the most under-recognised causes of recurring head pain in people who sit at desks, drive for a living, or spend hours at a screen. The good news is that because the source is mechanical, it usually responds well to the right treatment.

Why your neck can cause head pain

The top three joints of your cervical spine sit remarkably close to the nerve pathways that supply sensation to the back and sides of your head, your forehead, and even behind your eyes. There's a structure called the trigeminocervical nucleus where nerve signals from your upper neck and your face effectively share the same wiring in your brainstem. When the joints, discs, or muscles in your upper neck become irritated or stiff, your brain can genuinely struggle to tell the difference between "neck problem" and "head problem." The result is pain that you feel in your head, even though the fault lies a few centimetres lower down.

This is why treating the headache in isolation — with painkillers, or by resting in a dark room — often only takes the edge off. It doesn't address why the neck became irritated in the first place.

The everyday habits that set it up

Cervicogenic headaches rarely appear out of nowhere. They tend to build gradually, often from:

• Prolonged forward head posture at a desk or laptop, which loads the small joints at the top of the neck far more than most people realise
• Poor sleeping positions, particularly stomach sleeping or an unsupportive pillow that leaves the neck rotated for hours
• Stress-related muscle tension, especially through the upper trapezius and the muscles at the base of the skull
• A previous whiplash injury or old neck strain that never fully settled
• Training errors in the gym — heavy overhead pressing or poor form on rows can overload the neck and upper back if the surrounding muscles aren't strong enough to control the load

If you spend your working day at a screen and notice your headaches tend to build through the afternoon, or you wake up with neck stiffness that eases as the day goes on, this pattern fits.

How to tell if your headache is coming from your neck

A few clues tend to point towards a cervicogenic cause rather than a classic migraine or tension headache:

• The pain usually starts on one side and stays on that side
• It often begins at the base of the skull and spreads forward over the head, rather than starting behind the eyes
• Turning your head, looking up, or holding a sustained position (like scrolling on your phone) can bring it on or make it worse
• Pressing on specific tender points in the upper neck reproduces a familiar ache
• Your neck feels stiff or restricted, particularly when you try to look over your shoulder

None of this replaces a proper assessment, and headaches can have several causes at once, but this pattern is a useful starting point for working out what you're actually dealing with.

What actually helps

Because the cause is mechanical, cervicogenic headaches generally respond well to hands-on treatment combined with targeted exercise. A physiotherapy assessment will look at how well the joints in your upper neck move, how the deep neck flexors and postural muscles are working, and what's driving the irritation in the first place — whether that's desk setup, training load, or old injury. From there, treatment typically combines manual therapy to restore movement in the stiff segments with a structured pain relief approach to calm things down in the short term, alongside a graded strengthening programme so the neck can actually tolerate daily life without flaring up again.

Strengthening is often the piece people skip, but it's usually the difference between short-term relief and a headache that doesn't come back. Building endurance in the deep neck and upper back muscles — the kind of targeted strength and conditioning work a physio can guide you through — helps the neck cope with long days at a screen or heavier training loads without tipping back into pain.

When to get it checked

If your headaches are frequent, if painkillers are becoming a daily habit, or if you've noticed the neck stiffness and headache pattern described above, it's worth having it properly assessed rather than just managing around it. A thorough physiotherapy assessment can usually identify quite quickly whether your neck is the driver, and build a plan to deal with the cause rather than just the symptom.
