If your headaches sit on one side, start at the base of your skull, and flare when you turn your head or hold a posture too long, the pain may not be starting in your head at all. A cervicogenic headache is head pain that originates in the upper neck and is referred upward — and once the source is correctly identified, the treatment options change entirely.
What a cervicogenic headache is
A cervicogenic headache is pain that is generated by the structures of the upper neck — the joints, muscles, ligaments, and nerves of the top three cervical segments — but felt in the head or face. The mechanism is anatomical: the upper cervical nerves (C1–C3) share a relay station in the brainstem, the trigeminocervical nucleus, with the nerves that carry sensation from the head. Pain signals from an irritated neck structure arrive there and get "misread" as head pain (StatPearls: Cervicogenic Headache).
The classic picture is a one-sided headache that doesn't switch sides, is triggered or worsened by neck movement or sustained awkward posture, and comes with reduced neck range of motion (Sjaastad diagnostic criteria). Because that pain radiates up over the head, it is routinely mislabeled as migraine or tension headache — and it can genuinely coexist with them, which makes sorting out the source the first real step toward relief (cervicogenic headache and occipital neuralgia review).
Why it gets missed
Cervicogenic headache overlaps heavily with more familiar diagnoses. It can throb like a migraine, tighten like a tension headache, and even bring some light sensitivity along for the ride. Imaging often looks unremarkable, and a normal MRI can wrongly reassure everyone that "nothing is wrong."
What sets it apart is its behavior: it tracks with the neck. Provoking the pain by pressing on the upper neck, or reproducing it with certain head positions, is a meaningful clue. But physical examination alone isn't reliable enough to settle the question, because these signs overlap with other headache types (manual examination systematic review). That limitation is exactly why the diagnostic step below matters so much.
Confirming the neck is the source
The most reliable way to prove a headache is coming from the neck is to numb a specific cervical structure and watch what happens. A controlled diagnostic nerve block — placing local anesthetic at a targeted upper-cervical joint or the small nerves that supply it — does double duty. If the headache resolves when that structure is numbed, it confirms the neck as the pain generator; if it doesn't, it points you elsewhere (validation using controlled diagnostic blocks).
Just as importantly, a positive block predicts who will respond to targeted treatment. It turns the next decision from a guess into an informed one — you learn whether interrupting those specific nerves is likely to help before committing to anything more involved.
Targeted options when conservative care falls short
Cervicogenic headache is treated in a sensible order, least invasive first. Physical therapy focused on the upper neck, posture and ergonomic changes, and medications are the starting point, and many people improve with them.
When they don't, the diagnostic block opens the door to a precise next step. Radiofrequency treatment uses heat energy delivered through a fine needle to interrupt the specific cervical nerves carrying the pain signal — the same nerves the block identified. In people with stubborn, medication-resistant cervicogenic headache, pulsed radiofrequency targeting the mid-cervical nerve branches has produced satisfying, long-lasting relief without serious complications (pulsed radiofrequency for intractable cervicogenic headache). The evidence here is still growing and candidacy is individualized, but the appeal is real: the treatment is aimed squarely at the nerves the diagnostic block already flagged as responsible, rather than at the whole head.
The through-line is precision. Because a cervicogenic headache has an identifiable source, it can be confirmed objectively and treated at that source — instead of managed indefinitely as a generic headache.
