When Your Headache Starts in Your Neck

When Your Headache Starts in Your Neck

Not all headaches originate in the head. A significant subset — cervicogenic headaches — are driven by structures in the upper cervical spine: the joints, muscles, and connective tissue of the top three vertebral segments referring pain into the head, often as a steady ache behind one eye, across the forehead, or at the base of the skull.¹

Cervicogenic headache is frequently misdiagnosed as tension-type headache or migraine, and the distinction matters because the treatment is fundamentally different. Medication can manage symptoms, but it doesn't address the underlying mechanical problem generating the pain signal. A person who gets meaningful headache relief from manual therapy to the upper cervical spine almost certainly has cervicogenic headache, not a primary headache disorder.

The Anatomy Behind the Pattern

The upper three cervical segments (C1–C3) converge with the trigeminal nerve in the brainstem through a structure called the trigeminocervical nucleus. Because of this shared pathway, input from the neck — compression, irritation, restricted joint movement — can be perceived as head pain. It's the same mechanism that causes shoulder pain to be felt in the arm, or hip problems to generate knee symptoms: the brain localizes pain imprecisely, and the referred location can be far from the source.²

Common drivers include stiffness or hypomobility in the upper cervical joints, overload or guarding in the suboccipital and upper trapezius muscles, and sustained postures that load the upper neck — prolonged desk work, driving, looking down at a screen. The cervical spine is particularly sensitive to sustained positions because the muscles that stabilize it are designed for dynamic activity, not static holding.

How It Presents

Cervicogenic headache typically has a few distinguishing features: it's usually unilateral (one-sided), it tends to radiate from the back of the head forward, it can be provoked or reproduced by pressure on specific neck structures or by sustained neck positions, and neck movement or range of motion is often restricted or painful on the same side as the headache.¹

It may also coexist with other headache types, which complicates the picture. Someone with migraine can also have cervicogenic headache — and treating the cervical component often reduces overall headache frequency even if migraines still occur independently.

What the Evidence Supports

High-quality research — including a landmark randomized controlled trial by Jull and colleagues — demonstrated that a combination of manual therapy and specific therapeutic exercise for the deep cervical flexors produced significantly better outcomes for cervicogenic headache than either treatment alone, and both outperformed no treatment at 12-month follow-up.³

The exercise piece is particularly important and often underemphasized. The deep cervical flexors (longus colli and capitis) are the stabilizers of the upper cervical spine, and they are frequently inhibited in people with chronic neck pain and cervicogenic headache. Retraining their function — through cranio-cervical flexion exercises and progressive loading — addresses one of the root causes of the problem, not just the symptomatic tissue.

Load and the Neck

The cervical spine responds to load just like any other musculoskeletal structure. The issue is rarely that someone is doing too much — it's that the neck has been stuck in the same position for hours at a time without adequate movement variability, or that the stabilizing musculature isn't conditioned for the demands being placed on it.⁴

There are no postures that cause cervicogenic headache in isolation — only sustained loading patterns that exceed the tissue's tolerance over time. Regular movement breaks, varied neck positions, and a progressive strengthening program for the deep cervical flexors are protective. A neck that is strong and mobile handles sustained demands much better than one that is stiff and deconditioned.

Recognizing It and Getting It Right

A proper assessment for cervicogenic headache includes a thorough cervical spine examination — palpating the upper cervical joints to identify restricted or irritable segments, testing cervical range of motion, assessing deep flexor function, and screening for red flags that would warrant imaging or specialist referral.

If upper cervical joint findings reproduce the person's familiar head pain, the diagnosis is reasonably confident and the treatment direction is clear. If there are no cervical findings, the headache is less likely to be cervicogenic, and a different pathway is warranted.

The team at Boreal Spine & Sport regularly assesses the upper cervical spine as part of headache management — particularly for patients who haven't responded well to medication-focused approaches or whose headaches have a clear postural or positional pattern.
