NECK PAIN · WELDON SPRING
A headache that starts at the base of the skull and travels over one side of the head is usually coming from the neck, not the head.
Getting here from Weldon Spring
I-64 east to I-270 north, then the Natural Bridge exit — about twenty-five minutes. Parking outside the door.
The pattern that identifies it
Pain beginning at the top of the neck and traveling up and over, often reaching behind one eye, strictly one-sided, provoked by sustained neck position and eased by changing it. That is cervicogenic headache and it is common.
It is regularly carried under a migraine label for years, and the two genuinely overlap — nausea and light sensitivity occur in both. What separates them is the mechanical provocation and the side-locking.
Cervicogenic headache sets the comparison out properly.
Where it comes from
The upper three cervical segments share a relay in the brainstem with the trigeminal nerve, which supplies the face and front of the head. That convergence is why a joint at the top of the neck produces pain felt behind the eye.
It is not referred pain in a vague sense. It is a specific anatomical arrangement, and it explains why treating the neck resolves a headache that antimigraine drugs did not touch.
The examination that settles it
Pressing the joints and the nerve exit points at the base of the skull, and testing rotation with the neck flexed to isolate the top segment. If that reproduces your headache, the source is established without imaging.
The atlanto-axial joint is the one most often involved and the one least often assessed outside a clinic that does this specifically.
When a block is the answer
An occipital nerve block is diagnostic and therapeutic at once: if numbing the nerve abolishes the headache, the nerve is carrying it, and if it does not, the diagnosis moves on.
That second half only holds if the injectate reached the nerve, which is why it is image-guided rather than placed by feel. A negative result from a blind injection tells you nothing.
Medication, and what it will not do
Simple analgesia has a role in the short term. What it does not do is change a joint that is being loaded into a position it cannot tolerate, and an escalating medication plan for a mechanical problem manages the signal while the cause continues.
We are explicit about that early rather than after a year of prescriptions.
Posture correctors and what they achieve
Very little, and occasionally harm. A device that holds the shoulders back does the work the muscles should be doing, and the muscles adapt by doing less.
Endurance training achieves what the device only simulates: posture chairs and correctors covers the evidence, which is thinner than the marketing.
If the headaches change character
A headache pattern that alters — new location, new severity, or a first severe headache after fifty — warrants reassessment rather than continuing the existing plan.
That is a small proportion of cases and it is the reason we set review points rather than treating open-endedly.
What we will not do
We will not run an open-ended series of injections. A block is a treatment and a test; if two properly placed ones have not helped, that is a finding that should change the plan.
We are also not a route to ongoing opioid prescribing for headache. Opioids drive medication overuse faster than almost anything else and make a treatable headache disorder harder to treat.
If it is not the neck
Headache that is bilateral, that is not provoked by neck position, or that comes with visual aura is more likely primary headache and belongs on a different pathway.
New headache after fifty, scalp tenderness or jaw claudication needs urgent assessment rather than an appointment — temporal arteritis covers why.
The visit
An hour, mostly examination. What to expect describes it, and what the procedures feel like covers the part people actually want to know.
When both are true at once
Cervicogenic headache and migraine are separate diagnoses with separate mechanisms, and a good deal of writing on the subject treats them as alternatives. In practice they coexist more often than chance would predict, and treating the pair as an either-or question is a common route to partial results.
The overlap has a plausible basis. Cervical input converges on the same brainstem territory as the trigeminal system, so sustained nociceptive traffic from the upper neck lowers the threshold for a migraine attack. Running the other way, frequent migraine produces central sensitization that makes the neck structures more painful and more easily provoked.
The clinical consequence is specific: a patient with both may get a genuine but incomplete response to treatment aimed at either one, and that partial response is then misread as the treatment having failed.
So where the history suggests both, both are addressed — the cervical source with the examination and, where indicated, a diagnostic block, and the migraine on migraine principles. Improvement from a cervical intervention that reduces headache frequency without abolishing it is a result worth building on, not a negative finding.
What Weldon Spring patients ask
How is this different from migraine?
It is side-locked, provoked by neck position, and reproduced by pressing specific structures. Migraine is none of those reliably: the comparison.
Why would a neck problem cause pain behind my eye?
Because the upper neck and the trigeminal nerve share a brainstem relay. It is anatomy rather than coincidence.
Does the block hurt?
Briefly, and there is no sedation — you drive yourself home: what they feel like.
How far is it from Weldon Spring?
About twenty-five minutes via I-64 and I-270.
