The Headache That Isn't Coming From Your Head

Here's a pattern we see weekly in Bondi Junction. Someone has had headaches for years. They've seen the GP, possibly a neurologist. The head scan came back clear — good news that somehow felt like bad news, because the headaches didn't get the memo. They've cycled through every painkiller with a marketing budget. And in all that time, through all those appointments, nobody has properly examined the three joints at the top of their neck. Which is unfortunate, because for a very large share of chronic headache sufferers, that's where the headache lives.

The wiring problem behind it

The nerves from your upper cervical spine — the top three levels of your neck — feed into the same processing hub in the brainstem as the trigeminal nerve, which handles sensation for your head and face. The hub can't always tell whose signal is whose. So when an upper neck joint is restricted, inflamed or under sustained postural load, its complaints get routed upward and experienced as head pain: base of the skull, behind one eye, across the temple. The neck files the grievance; the head takes the blame. This is a cervicogenic headache — literally 'generated by the neck' — and it's among the most commonly misdiagnosed conditions we encounter.

The tells: is your headache one of these?

• It starts at the back of the head or upper neck and creeps forward — often ending behind one eye.
• It favours one side, and usually the same side. (Migraines can swap sides; cervicogenic headaches tend to be loyal.)
• It shows up after long desk days, long drives, or hours on the phone — and has a suspicious fondness for Thursdays, when the week's postural load peaks.
• Your neck is stiff or 'off' even on days the head doesn't hurt, and pressing the muscles just below your skull finds spots that are tender and weirdly familiar.
• Painkillers postpone it rather than prevent it. The supply line is intact, so the deliveries continue.

Three or more of those, and your headaches have earned a proper cervical assessment. The full picture of how we do that is on our headaches and migraines page.

'But I was told they're migraines'

Maybe they are — true migraines are a distinct neurological event, and we're not in the business of overturning a neurologist's diagnosis from a blog post. But two things are simultaneously true. First, cervicogenic headaches are misdiagnosed as migraines often enough that the research literature keeps writing about it; the symptoms overlap and the neck is rarely examined. Second, even for genuine migraine sufferers, upper-neck dysfunction is a recognised trigger — and trigger reduction is the cheapest migraine strategy there is. Either way, the neck deserves an examination it has probably never had. A clear head scan plus persistent headaches isn't a dead end; it's an arrow pointing slightly south.

Why the office is the natural habitat

Forward head posture — the universal souvenir of screen work — parks your 5kg head several centimetres in front of its support structure, multiplying the load on exactly the joints that refer pain into the head. Hold that all day, every day, and those joints stiffen, inflame, and start transmitting. It's why the Thursday-afternoon headache is practically a Bondi Junction office tradition, and why treating the headache without treating the posture pattern feeding it is a subscription service. Our desk worker page covers the occupational side in full.

What actually stops them

Assessment first: joint-by-joint testing of the cervical spine, posture measurement, and EOS standing imaging where clinically indicated (very low dose, bulk billed through Medicare, no referral needed) — because seeing a flattened cervical curve on your own scan tends to make years of headaches suddenly, almost annoyingly, make sense. Then correction: restoring motion and alignment to the segments doing the referring, alongside fixing the postural inputs so the problem stays fixed. A defined plan, progress reviews, an endpoint. Headache patients are often among our faster responders — the honest version of how fast comes after your assessment, not before it.

Quick answers

Can a chiropractor really help headaches?

For cervicogenic headaches — yes, that's precisely the mechanism chiropractic addresses. For migraines with a cervical trigger, reducing the trigger reduces the frequency for many people. The assessment sorts out which you have.

Why does my headache sit behind one eye?

That's the classic referral pattern from the upper cervical joints — the shared wiring routes their signal to the front of the head, commonly behind the eye on the same side as the restricted joint. Loyal to one side is the cervicogenic signature.

Headaches and sinus pressure together?

Common combination with its own two-way logic — we wrote a whole article on the sinus-neck connection, which several thousand congested people a month seem to appreciate.
