Quick Answers — Headaches After a Car Accident
Why do headaches occur after a car accident? Post-accident headaches can originate from the cervical spine (cervicogenic), the brain (post-concussion), or specific nerves (occipital neuralgia). Identifying the source is essential for appropriate treatment.
Are headaches after a car accident serious? Persistent headaches following a collision — particularly those worsening with cognitive effort, screen use, or exertion — warrant objective clinical evaluation for cervicogenic dysfunction or post-concussion involvement.
Can a car accident cause headaches weeks later? Yes. Post-traumatic headaches frequently persist or worsen in the weeks following a collision, particularly when cervical instability or post-concussion syndrome is present.
What is the most common type of headache after a car accident? Cervicogenic headaches — originating from the cervical spine facet joints and muscles — are among the most common post-accident headache types. Post-concussion headaches are also frequent, even without direct head impact.
Types of Headaches After a Car Accident
Cervicogenic headaches originate from the cervical spine. They typically begin at the base of the skull and radiate forward toward the forehead, temples, or behind the eyes. They are worsened by neck movement and sustained postures. The source is injury to the cervical facet joints, muscles, and upper cervical ligaments — not the brain. Cervicogenic headaches respond to treatment directed at the cervical spine.
Post-concussion headaches originate from neurological disruption following the acceleration-deceleration forces of the collision. They are triggered or worsened by cognitive effort, screen use, physical exertion, and sensory stimulation. They frequently accompany other post-concussion symptoms — light sensitivity, dizziness, cognitive fog. They indicate neurological involvement even when CT imaging is normal and even when no direct head impact occurred.
Occipital neuralgia produces sharp, shooting, or burning pain originating at the base of the skull and traveling along the back and top of the head. It results from irritation or compression of the occipital nerves — often from cervical muscle tension or upper cervical joint injury following a collision.
Tension-type headaches following a car accident reflect sustained cervical muscular hypertonicity — the chronic muscle guarding that develops as the cervical musculature attempts to compensate for ligamentous instability. These are among the most common post-accident headache types and often improve as cervical treatment progresses.
Why Headaches After a Car Accident Are Frequently Missed
Standard emergency evaluation does not evaluate the cervicogenic or post-concussion mechanisms that produce most post-accident headaches. A normal CT scan rules out intracranial hemorrhage — it does not evaluate cervical facet joint injury, upper cervical ligamentous instability, or the oculomotor dysfunction that characterizes post-concussion headaches.
Post-accident headache patients who are discharged from the emergency room with normal imaging and told their symptoms will resolve are frequently living with unidentified cervicogenic dysfunction or post-concussion involvement that requires specific clinical management.
How Cityside Chiropractic Evaluates Headaches After a Car Accident
Clinical History and Headache Characterization identifies headache type, onset pattern, triggering factors, and associated symptoms — distinguishing cervicogenic from post-concussion from occipital neuralgia presentations.
Cervical Range of Motion Analysis quantifies the cervical restriction contributing to cervicogenic headache patterns.
RightEye Computerized Vision Tracking identifies the oculomotor dysfunction — smooth pursuit deficits, saccadic abnormalities, fixation instability — that characterizes post-concussion headaches. This objective finding confirms post-concussion involvement when screen and exertion-triggered headaches are present.
BTrackS Balance Assessment evaluates the vestibular dysfunction that frequently accompanies post-concussion headaches.
PostureRay CRMA Mensuration identifies upper cervical instability when the headache pattern and clinical examination suggest ligamentous involvement at C1-C2 or C2-C3 — levels whose instability characteristically produces occipital and cranial headache patterns.
When headache characteristics suggest intracranial pathology, imaging referral is initiated. When post-concussion syndrome is established, neurological referral for coordinated management is recommended as indicated.
Case Example — Headaches After a Car Accident
A patient presented 10 days after a rear-end collision with daily headaches beginning at the base of the skull and radiating to the right temporal region, worsening significantly with computer use and fluorescent lighting. No direct head impact had occurred. CT at the emergency room had been negative.
RightEye evaluation revealed smooth pursuit accuracy below the 12th percentile and saccadic intrusions — consistent with post-concussion oculomotor dysfunction. BTrackS balance assessment showed deficit outside normative range. Cervical range of motion was restricted 45% in rotation.
CRMA mensuration identified upper cervical instability at C2-C3 — providing a structural basis for the occipital headache component alongside the post-concussion findings.
The objective documentation distinguished the headache as having both cervicogenic and post-concussion components — directing a treatment approach that addressed both sources and providing the clinical evidence for the patient's personal injury claim.
Frequently Asked Questions
Can whiplash cause headaches? Yes. Whiplash injury to the upper cervical facet joints and ligaments is among the most common causes of post-accident headaches — producing the cervicogenic headache pattern that begins at the base of the skull.
Do post-accident headaches go away on their own? Mild cervicogenic headaches often improve with appropriate cervical treatment. Post-concussion headaches and those associated with cervical instability may persist without specific clinical management.
Can a car accident cause migraines? Existing migraine conditions can be exacerbated by car accidents. Post-traumatic headaches can also present with migraine-like characteristics. Clinical evaluation determines whether the headache represents a new post-traumatic condition or exacerbation of a pre-existing one.
For Personal Injury Attorneys
Post-accident headache cases are frequently minimized by carriers arguing that headaches are subjective and non-specific. Objective identification of the specific headache source — upper cervical instability on CRMA, oculomotor dysfunction on RightEye, vestibular deficits on BTrackS — transforms headache complaints into documented, mechanism-specific clinical findings.
