Cervicogenic Headache

See a clinician for headache

Headache has a wide range of causes, most benign and a few not. Nothing on this page is a diagnosis, and self-diagnosing headache is a genuinely poor idea.

Seek urgent medical attention for: a sudden severe headache unlike any you have had before; headache with fever, neck stiffness, or rash; headache following head trauma; headache with neurological symptoms such as weakness, numbness, visual loss, confusion, or difficulty speaking; headache that wakes you from sleep; or a headache pattern that has changed noticeably.

Why the neck can cause head pain

The anatomical basis is a convergence in the brainstem.

Sensory input from the upper three cervical nerve roots (C1–C3) and sensory input from the trigeminal nerve — which supplies the face and much of the head — converge on the same region of the brainstem, the trigeminocervical nucleus.

Because these inputs share a processing area, the brain can misattribute the origin of a signal. Nociception arising from an upper cervical joint, disc, or muscle can be experienced as pain in the head — typically the back of the head, the temple, or behind the eye.

The structures usually implicated are the C2–C3 facet joint, the atlanto-occipital and atlantoaxial joints, the upper cervical discs, and the suboccipital musculature.

How it is characterised

Cervicogenic headache is generally described as:

• Unilateral, and not switching sides between episodes
• Starting in the neck or back of the head and spreading forward
• Provoked by neck movement or sustained neck position
• Associated with reduced cervical range of motion, particularly upper cervical rotation
• Sometimes accompanied by ipsilateral shoulder or arm discomfort
• Not typically accompanied by the nausea, vomiting, and light sensitivity characteristic of migraine — though there is overlap and this is not a reliable discriminator on its own

The side-consistency is the feature clinicians tend to weight most: a headache that alternates sides between episodes is unlikely to be cervicogenic.

Why the distinction matters

Migraine, tension-type headache, and cervicogenic headache are managed differently, and the overlap between them is substantial enough that misclassification is common in both directions.

Cervicogenic headache is also frequently under-recognised, because the pain is felt in the head and the source is in the neck — so the neck does not get examined.

Conversely, plenty of people with neck pain and headache have migraine with neck symptoms, which is common and is not cervicogenic headache. Treating one as the other wastes time.

This is a clinical distinction requiring examination — assessment of upper cervical movement, palpation of the relevant segments, and sometimes diagnostic blocks. It is not determinable from symptom description alone, which is why this page describes rather than diagnoses.

What is known about treatment

Manual therapy and specific exercise both appear in the evidence-based management of cervicogenic headache, and the exercise component typically emphasises deep cervical flexor training and upper cervical motor control rather than general strength work.

That is the same theme that runs through the neck pain page: where exercise helps cervical conditions, the exercise is often low-load endurance and control work rather than loading. It is unglamorous, produces no visible change, and is not what “strengthen your neck” usually means.

This site does not provide a protocol for it. The reasons are the ones given across this section: the exercise that helps depends on what is actually going on, doing craniocervical flexion work with the wrong pattern reinforces the fault it is meant to correct, and neither of those can be assessed remotely.

What this means if you train your neck

If you get headaches during or after neck training, stop and get assessed. That is listed on the safety page among the symptoms that mean stop rather than adjust — particularly headache beginning at the base of the skull.

If you have diagnosed cervicogenic headache, whether and how to train is a question for whoever is managing it. Upper cervical structures are involved, and upper cervical structures are exactly what rotation and extension work load.

If you have unexplained headaches, work out what they are before adding neck training to the picture. Not because training is likely to be harmful, but because introducing a new variable into an unexplained symptom makes the eventual explanation harder to reach.

The limits of this page

Cervicogenic headache is a contested diagnostic category with genuine disagreement in the literature about its prevalence and its boundaries with migraine. This page presents the mainstream description and does not attempt to resolve those disputes.

If you want the underlying anatomy, the muscles of the neck page covers the suboccipital group — four small muscle pairs at the base of the skull with among the highest density of muscle spindles anywhere in the body, and frequent participants in this conversation.
