What Is Cervicogenic Headache and How Is It Caused by a Crash?

Cervicogenic means the pain source is in the neck

Cervicogenic headache is a secondary headache, meaning another condition is considered responsible for the head pain. The pain is felt in the head even though the suspected source is a structure in the neck. The International Headache Society describes cervicogenic headache as headache caused by a cervical-spine or neck soft-tissue disorder, usually but not always accompanied by neck pain.

A similar symptom description can occur with other headache disorders. The name should follow evidence connecting the headache to a neck disorder rather than being used for every headache that begins after a collision.

A crash timeline is relevant but not conclusive

Rapid head and neck movement can occur in rear, side, and front impacts. Mayo Clinic lists neck pain, stiffness, reduced movement, and headache among common whiplash symptoms. The International Headache Society separately classifies headaches attributed to trauma or injury to the head or neck.

That distinction matters because a post-traumatic headache should not automatically be relabeled cervicogenic based only on the crash date. Record whether head pain began with the neck symptoms, whether neck movement reliably changes it, and whether both improve or worsen together. Those observations support evaluation but do not replace it.

Rule out head-injury danger signs first

Call 911 or seek emergency care for a headache that worsens and does not go away, especially with recurring vomiting, seizure, weakness, numbness, lowered coordination, slurred speech, increasing confusion, unequal pupils, loss of consciousness, or inability to wake. The CDC lists these as concussion danger signs. A neck-related headache and concussion can occur after the same event, so one should not be used to rule out the other.

MedlinePlus summarizes concussion symptoms, including headache, dizziness, nausea, vision problems, fatigue, and cognitive changes. Report the complete pattern.

Diagnosis requires a supported neck connection

The evaluation may include headache history, neck movement, neurological findings, tenderness, and the way symptoms respond to particular actions. Imaging may help answer selected structural questions, but an image alone does not prove the source of pain. The VA/DoD headache guideline describes cervicogenic headache as requiring evidence of a cervical disorder and evidence that the disorder is causing the headache. Temporal relation, parallel improvement, reduced neck motion with provocation, and response to a diagnostic block are among the criteria clinicians may consider.

Ask what evidence links the neck finding to the headache and what competing diagnoses have been considered. A careful answer should separate a suspected source from a confirmed one.

• Headache location, side, quality, and frequency
• Relationship to neck pain and movement
• Dizziness, nausea, vision, and cognitive symptoms
• Earlier headaches, neck injuries, and concussion history
• Findings that support or weaken a cervical source

Treatment should follow the diagnosis

The appropriate plan depends on the cause, current neurological findings, severity, and other health conditions. Options may involve education, medication, exercise or rehabilitation, or other care selected by the evaluating clinician. If chiropractic or manual care is considered, ask which finding supports the method, what alternatives exist, how benefit and side effects will be measured, and which symptom would stop care or prompt referral. No single procedure fits every post-crash headache.

Use a specific review point, such as headache days, neck movement, screen tolerance, driving safety, or a work task. A new neurological sign or worsening headache should trigger reassessment rather than automatic continuation.
