Neck pain before a migraine: trigger or symptom?

Short answer

Both, but far more often a symptom. Neck pain is one of the most common features of a migraine attack — more common in migraine than in most people realise — and in the majority of cases it starts with the headache or within the two hours before it. That makes it part of the attack, not the thing that set it off.

The number that reframes this: a systematic review and meta-analysis of 24 clinic-based studies covering 4,352 people with migraine found a pooled neck pain prevalence of 77.0%, against 23.2% in people without headache disorders — roughly twelve times more common. In chronic migraine it reached 87.0%. (journals.sagepub.com)

And no, you did not sleep on it wrong. If you have been told for years that your migraines come from posture, or a bad pillow, or tension you should manage better, that story has been examined and it mostly does not hold. Neck pain in migraine has a described mechanism that has nothing to do with how you sit. It is also, quietly, one of the reasons migraine goes undiagnosed for so long — people take the neck to a physiotherapist and never mention the headache to a neurologist.

There is one genuinely decisive piece of evidence, and it arrived in 2025. In a phase 3 randomised trial, a migraine drug taken before any pain started — during the early phase — cleared the pre-headache neck pain: at three hours, neck pain was absent in 28.9% of treated events against 15.9% on placebo. (doi.org) A migraine drug relieves it. That is about as close as clinical evidence comes to saying the neck pain is the migraine.

If your neck has been the thing you notice first for years and nobody has ever looked at the pattern behind it, this is a reasonable starting point: take the 2-minute check-in — it maps what is building in your nervous system behind the headache pattern.

Why does migraine cause neck pain at all?

Because the nerves that carry pain from your head and the nerves that carry pain from your upper neck arrive at the same place.

The pain fibres of the trigeminal nerve — the nerve that serves the face and the coverings of the brain — and the sensory nerve roots from the top three segments of the neck converge onto shared second-order neurons in the brainstem and upper spinal cord. That shared junction is called the trigeminocervical complex. It has been shown directly in experiment: stimulating the dura mater increases how strongly those same neurons respond to input from the neck. (doi.org) When the complex is sensitised during a migraine, the brain has no clean way to tell which input the signal came from. Head pain is felt in the neck; neck input feeds the head pain.

That is not a metaphor for tension. It is anatomy, and it means the neck symptom can be generated centrally, by the attack, with nothing wrong in the neck at all.

It also cuts the other way, which is why this article is not simply "ignore your neck." Because the convergence runs in both directions, genuine irritation in the upper cervical joints can feed nociceptive input into the same complex. A study that palpated the upper cervical spine in 179 people with migraine and 73 headache-free controls found they split into three groups: 11% felt nothing, 42% had local neck pain only, and 47% had pain that referred into the head under sustained pressure. (doi.org) Nearly half of people with migraine have an upper cervical spine that reproduces their head pain when pressed. That is a real musculoskeletal finding sitting inside a neurological disorder.

When exactly does the neck pain start?

This is the question that settles "trigger or symptom," and one study was designed specifically to answer it.

Researchers followed 487 people with episodic migraine and asked precisely when neck pain appeared relative to the headache. 69.4% reported neck pain at some point during the migraine. Of those:

• 54.4% — neck pain started with the headache

• 24.2% — neck pain started within 2 hours before the headache

• 7.4% — neck pain started 2 to 48 hours before the headache

In the group whose neck pain began within two hours, the neck pain progressed into the headache phase in 82.2% of cases. The authors concluded that neck pain is far more likely to be part of the migraine attack than a prodromal symptom. (link.springer.com)

So: about four in five people with migraine-related neck pain get it at the same time as the headache or in the two hours before. That is not a trigger window. That is the attack arriving, with the neck first through the door.

Is neck pain a warning sign before a migraine?

For a minority it genuinely is, and for them it is one of the most useful warnings available.

Neck pain shows up near the top of every list of early migraine symptoms. In the PRODROME dataset — 920 participants, 4,802 logged early-symptom events — neck pain was the third most common, present in 41.9% of events, behind light sensitivity (57.2%) and fatigue (50.1%). (pmc.ncbi.nlm.nih.gov) An older electronic diary study found a stiff neck in 50% of attacks with warning features. (neurology.org) In a study of 1,010 people at a headache centre, a tense neck was the single most frequent early symptom starting two or more hours before the pain. (link.springer.com) In the REFORM cohort of 632 people, neck pain was the third most common early symptom at 33.2%. (journals.sagepub.com)

How does that square with the 7.4% figure above? They are measuring different things. The timing study asked when neck pain started in an attack and found it usually starts late. (If you are trying to work out whether something you noticed was an early warning or a cause, that is a different question with a different answer.) The prodrome studies asked what people notice during the early phase and found neck pain near the top. Both are true: neck pain is usually part of the attack, and when someone does get a genuine early warning, neck stiffness is one of the commonest forms it takes.

The practical translation is personal rather than statistical. Over your next five attacks, note the hour your neck starts and the hour your head starts. If the gap is consistently more than two hours, you have a warning window. If the neck and the head arrive together, you don't — and no amount of neck treatment will change that.

Could it be a neck problem instead of migraine?

Sometimes, and the distinction has a name: cervicogenic headache. It is head pain genuinely referred from a structural problem in the neck, and it is a different diagnosis with different treatment.

A few features point that way rather than toward migraine:

• Pain that starts in the neck and always spreads the same direction, typically one-sided and from back to front, without switching sides between episodes.

• Head pain reproduced by neck movement or by pressure on the upper neck — and reliably, not occasionally.

• Restricted neck range of motion on that side.

• Absence of the migraine package: no nausea, no light or sound sensitivity, no throbbing, no worsening with routine activity.

Migraine, by contrast, moves sides across attacks, comes with sensory sensitivity and often nausea, and throbs. The overlap is real — plenty of people have both — which is one reason a physiotherapist and a neurologist can look at the same neck and see different things.

The risk to avoid is the common one: spending two years on the neck because the neck is what hurts first, while a treatable migraine goes unnamed. About half of migraine is never formally diagnosed, and telling a headache from a migraine is where that starts, and without a diagnosis nothing downstream — acute treatment timing, prevention, workplace accommodations — is really available.

Does treating the neck help migraine?

Partly, and worth trying — as an addition rather than a replacement.

The logic follows the anatomy. If nearly half of people with migraine have upper cervical joints that refer pain into the head under pressure (doi.org), then reducing that input reduces one stream feeding a sensitised trigeminocervical complex. That is a reasonable target for manual therapy, targeted neck and upper-back strengthening, and attention to prolonged static postures.

What it will not do is stop attacks generated centrally. If your neck pain begins with the headache — the 54.4% pattern — then the neck is downstream, and treating it is treating a symptom. Useful for comfort, not preventive.

A fair expectation: neck work may reduce how much the neck hurts and may take the edge off attacks in the people with genuine cervical involvement. It will not replace migraine treatment, and a practitioner who tells you your migraines are purely a neck problem is over-claiming.

The single most important thing to get right is timing of acute medication. Migraine treatment works substantially better taken early, while pain is still mild. If neck stiffness is your reliable first sign, that stiffness is your cue to act — not your cue to stretch and hope.

What does the evidence not show?

Three limits worth stating.

The prevalence figures are heterogeneous. The 77.0% pooled estimate carries a confidence interval of 69.0–86.4%, and these are clinic-based studies — people who sought specialist care, which selects for more severe and more chronic migraine. (journals.sagepub.com) The true figure in the general migraine population is likely lower.

"Premonitory" research generally is shakier than it sounds. A systematic review found pooled prevalence of at least one early symptom ranging from 29% in population-based studies to 66% in clinic-based ones, with very high heterogeneity, and concluded the evidence was insufficient to characterise the phase reliably. (link.springer.com) The phenomenon is real; the percentages are soft.

Nobody has shown that treating the neck prevents migraine attacks. The mechanistic case is good and the symptom relief is plausible. A randomised trial showing fewer monthly migraine days from cervical treatment alone is not something this article can point you to.

When should you see a doctor?

See a clinician if headaches are becoming more frequent, if you use acute painkillers on 10 or more days a month, if attacks are disabling, if the pattern has changed, or if you have never had a formal headache diagnosis. Also see someone if neck pain is persistent between attacks, rather than only around them — that is a different question and deserves its own examination.

Seek urgent care for a headache that peaks within a minute, a headache after a head injury, neck stiffness with fever, a first severe headache after age 50, or any headache with weakness, numbness, confusion, seizure, vision loss, or changed consciousness.

Before that appointment, it helps to know what your own pattern looks like: take the 2-minute check-in — it shows the buildup in your nervous system that sits behind the headache pattern, which is the part a neck examination cannot see.

How to bring this up with your doctor — and what to ask for

Bring the timing, not the adjective. For your last five episodes, write the hour the neck started and the hour the head started. "Neck at 2pm, head at 4pm, four times out of five" is clinical information. "My neck is always tight" is not.

Say the sentence that changes the frame. Try: "My neck pain comes with my headaches, not separately. Could the neck pain be part of the migraine rather than causing it?" That one question moves the conversation from musculoskeletal to neurological, which is where it usually belongs.

Ask these specifically. Does my pattern fit migraine or cervicogenic headache? If neck stiffness is my earliest sign, should I take acute medication then rather than waiting for pain? How many days a month can I use it before risking medication-overuse headache? Given my frequency, am I a candidate for preventive treatment? Is a physiotherapy referral worth adding alongside — not instead of — migraine treatment?

Bring three numbers. Headache days per month, acute medication days per month, days you couldn't work or function. Those drive most treatment decisions.

If you are dismissed. "Can you note in my record that I asked whether my neck pain is part of a migraine and we decided not to pursue it?" A question on the record gets revisited more often than one that isn't. And ask about a referral to a headache specialist — migraine care varies enormously between a general clinic and a headache service.

How Welltory helps

Welltory does not measure neck pain, does not detect migraines, and does not predict attacks. Our own data section above says exactly what we can and cannot see, including a finding that failed our verification check.

What the app gives you is the continuous record a symptom diary can't: resting heart rate, heart rate variability, sleep, and daily load, measured the same way every day against your baseline rather than a population average. When you go back to look at the days around an attack, those measurements were taken without you having to remember — which matters, because the hours when a migraine is starting are the hours you are least able to observe yourself accurately.

And the brain fog figure is worth taking personally. If you live with migraine and have been treating your foggy days as a focus problem, roughly half the people in your situation report the same thing. It is part of the condition, not a character trait, and it is a reasonable thing to raise with a clinician.

How we made it

The clinical content rests on headache-medicine literature: the neck pain prevalence meta-analysis (Al-Khazali et al. 2022), the timing study that separates prodrome from attack (Lampl et al. 2015), the cervical palpation stratification study (Luedtke et al. 2017), the largest prodrome dataset (the PRODROME screening period), and the phase 3 trial treating the premonitory phase (Goadsby et al. 2025). We included the counter-evidence deliberately: the meta-analysis questioning premonitory prevalence estimates, and the absence of any trial showing neck treatment prevents attacks.

The data section uses Welltory's own curated cohort: 4,145 users with wearable-quality data, 396 of whom report migraine in an onboarding survey. Every candidate metric was tested against a verification gate — a difference only counts if it holds within strata of how many other conditions a person reports. Resting heart rate failed that gate and is reported here as failing it. Brain fog passed. We do not measure neck pain and we have no attack log, so no claim is made about either.
