βHeadaches are one of the most common complaints in clinical practice, frequently labeled as Migraines or Tension-Type Headaches. However, when patients do not respond to neurological medications or stress management, the true source of the pain is often cervical: Cervicogenic Headache (CGH).
βRecent literature emphasizes that the upper cervical spine is a major, yet frequently overlooked, pain generator for unilateral headaches, largely due to the complex neuroanatomy connecting the neck and the head.
βπ What Is a Cervicogenic Headache?
βCGH is a secondary headache disorder originating from dysfunction in the cervical spine or its surrounding soft tissues, typically involving the C1-C3 spinal segments.
βBecause the nerves supplying the upper neck share a pathway with the nerves supplying the face and head, dysfunction in the neck translates into head pain.
βπ Pathophysiology
βThe mechanism relies on a critical anatomical junction: the trigeminocervical nucleus (TCN) in the upper spinal cord.
βAfferent nerve fibers from the upper three cervical nerve roots (C1, C2, C3) and the trigeminal nerve (cranial nerve V) converge here. When joints, ligaments, or muscles in the upper cervical spine are inflamed or restricted, the brain misinterprets these pain signals as originating from the forehead, eyes, or temples (the trigeminal nerve distribution).
βπ Typical Pain Distribution
βPatients typically present with:
ββ’ Unilateral pain that starts in the suboccipital region (base of the skull)
β’ Pain radiating forward to the temporal, frontal, or orbital (around the eye) regions
β’ A dull, non-throbbing ache that can occasionally become sharp
β’ Pain that is mechanically provoked by awkward neck postures or sustained reading/screen time
βπ Key Clinical Signs
βSeveral clinical findings can suggest CGH over a migraine:
ββοΈ Positive Cervical Flexion-Rotation Test (CFRT): A significant restriction (loss of 10 degrees or more) in upper cervical rotation when the neck is fully flexed
βοΈ Pain reproduced by deep palpation of the upper cervical facet joints (C2-C3) or the greater occipital nerve
βοΈ Restricted active cervical range of motion
βοΈ Ipsilateral shoulder or arm pain (occasionally accompanying the headache)
βπ Why It Is Frequently Misdiagnosed
βBecause the primary symptom is head pain, it frequently mimics:
ββ’ Migraine without aura (especially since CGH can sometimes cause nausea)
β’ Tension-type headaches
β’ Occipital neuralgia
βπ Evidence-Based Treatment Approaches
βTreating the head won't fix a neck problem.
π βConservative management
ββ’ Sustained Natural Apophyseal Glides (SNAGs) focusing on C1-C2 rotation
β’ Deep neck flexor (craniocervical flexion) strengthening to restore postural control
β’ Manual therapy targeting upper cervical joint mobilization
β’ Postural re-education to reduce forward head posture
π βInterventional options
ββ’ Diagnostic and therapeutic nerve blocks (e.g., greater occipital nerve block)
β’ Radiofrequency ablation of the C2-C3 facet joint nerves in severe, refractory cases
βπ Clinical Takeaway
βIf a patient complains of a one-sided headache that worsens with desk work or driving, always clear the upper cervical spine. A simple Cervical Flexion-Rotation Test can instantly differentiate a true migraine from a neck issue, guiding the patient to the right treatment rather than lifelong medication.
