Are Your Headaches Coming From Your Spine? A Cervicogenic Headache Explainer.

There's a type of headache that neurologists often struggle to treat because it doesn't originate in the brain. It originates in the neck. It's called a cervicogenic headache (CGH), and it's frequently misdiagnosed as tension headache or migraine, which means patients spend years on medications that don't address the actual problem.

If that sounds familiar, keep reading.

What Is a Cervicogenic Headache?

A cervicogenic headache is a secondary headache, meaning it's caused by another structure, specifically the cervical spine. Pain signals from the upper cervical joints, discs, muscles, or nerves can refer into the head through the trigemino-cervical complex, a region in the brainstem where upper cervical nerve input and trigeminal nerve input converge.

In plain language: your neck is sending pain signals that your brain interprets as a headache. The head hurts, but the source is the neck.

A 2024 review in Best Practice & Research Clinical Rheumatology outlined the diagnostic features and treatment approach for cervicogenic headache, emphasizing that the condition is often underdiagnosed because it requires examination of the cervical spine rather than the head alone to identify.¹

How to Recognize a Cervicogenic Headache

Cervicogenic headaches have a distinct clinical profile. Not every feature needs to be present, but most CGH patients report several of the following:

• Unilateral pain that doesn't switch sides: the headache always comes from the same side
• Pain that starts at the base of the skull (occiput) and radiates forward toward the eye, forehead, or temple
• Neck stiffness or reduced range of motion associated with or preceding the headache
• Pain triggered or reproduced by neck movement or sustained neck positions (looking down, turning to one side)
• Tenderness at the upper cervical joints on physical examination, particularly at C1-C2-C3
• History of neck trauma (whiplash, sports injury) or significant desk work

Unlike migraine, cervicogenic headaches typically lack the nausea, visual aura, and photophobia that characterize true migraine. Unlike tension headaches, they're associated with clear cervical dysfunction on examination rather than diffuse muscle tenderness alone.

The Role of the Upper Cervical Joints

The upper three cervical levels (C1, C2, C3) are the most common sources of cervicogenic headache. These joints are innervated by branches of the cervical dorsal rami, which converge in the brainstem with pain fibers from the trigeminal nerve, the main pain nerve of the face and head. This convergence is why restriction, inflammation, or injury at C1-C3 can generate referred pain into the scalp and face.

Research published in Musculoskeletal Science and Practice highlighted that clinical evaluation of the upper cervical spine, including manual examination of joint mobility and reproduction of the patient's headache with specific palpation, is essential for accurate diagnosis and treatment planning.²

Why Chiropractic Works for This Type of Headache

If the cause is a restricted or dysfunctional cervical joint, the treatment needs to address that joint directly. This is why chiropractic care is specifically included in evidence-based clinical practice guidelines for cervicogenic headache.

A 2026 clinical practice guideline published in the Journal of Integrative and Complementary Medicine, developed by a team of chiropractic researchers and clinicians, recommends spinal manipulative therapy as a primary treatment approach for adults with cervicogenic headache, alongside mobilization and specific rehabilitative exercises.³

The mechanism makes intuitive sense: if a restricted upper cervical joint is generating the pain signal, restoring normal motion to that joint removes the irritant. Most patients with true CGH notice immediate improvement in both neck mobility and headache frequency with directed chiropractic care.

Getting an Accurate Diagnosis

The starting point is a thorough cervical examination: range of motion testing, palpation of the upper cervical segments, and a headache history that looks at trigger patterns. If your headache can be partially reproduced by pressing on the upper cervical joints and temporarily relieved by manual techniques, that's strong evidence for a cervicogenic source.

We see a significant number of headache patients in our Round Rock clinic who have been prescribed migraine medications for years when the actual problem is cervical joint dysfunction responding beautifully to chiropractic adjustment and neck pain treatment. If that's your situation, a single evaluation could change your entire approach.
