Headache & Migraine After Concussion
Post-concussion headache is the most common persistent symptom after concussion — and one of the most undertreated. The reason most treatments fail is that headache after concussion is not a single condition. It is a symptom generated by five distinct neurologic mechanisms, each requiring a different approach. This guide explains what drives post-concussion headache, why it persists, and what effective treatment looks like.

Why Headaches Persist After Concussion
Headache is the most common symptom reported after concussion, affecting 70–90% of patients in the acute phase. For most people, headaches resolve within 4–12 weeks. For a significant minority, they persist for months or years — not because the brain is permanently damaged, but because the neurologic system generating the headache has not been correctly identified and treated.
The critical insight is that post-concussion headache is a symptom, not a diagnosis. The same headache presentation can be driven by cervical spine dysfunction, vestibular disruption, autonomic dysregulation, oculomotor impairment, or migraine-type neurologic sensitization — and each of these requires a completely different treatment approach.
Treatments that target headache as a symptom (pain medication, rest, generic physical therapy) produce inconsistent results because they do not address the underlying neurologic constraint. Constraint-based evaluation identifies which system is generating the headache and sequences treatment accordingly.
Common Treatment Failures
The Five Types of Post-Concussion Headache
Each type has a distinct mechanism, a distinct symptom pattern, and a distinct treatment approach. Identifying which type is primary — or which combination is present — is the foundation of effective care.
Cervicogenic
Pain originating from the cervical spine and referred to the head. Often one-sided, triggered by neck movement or sustained posture.
- One-sided or occipital pain
- Neck stiffness
- Triggered by posture
- Reduced cervical range of motion
Vestibular-Driven
Headache generated by sensory mismatch when the vestibular system fails to accurately process head movement and spatial orientation.
- Worsens with movement
- Associated dizziness
- Crowd or screen sensitivity
- Pressure or fullness sensation
Autonomic / Vascular
Headache driven by dysregulation of blood flow and pressure, often worsening with exertion, position change, or heat.
- Worsens with exertion
- Positional component
- Associated fatigue
- Exercise intolerance
Oculomotor
Headache generated by the increased effort required to maintain visual stability when eye movement control is impaired.
- Frontal or periorbital pain
- Worsens with reading/screens
- Eye strain
- Blurred or double vision
Migraine-Type
Migraine-pattern headache triggered or worsened by concussion, often with light/noise sensitivity, nausea, and throbbing quality.
- Throbbing quality
- Light & noise sensitivity
- Nausea
- Aura in some patients
Vestibular Migraine
Vestibular migraine is one of the most commonly missed diagnoses in patients with persistent post-concussion symptoms. It occurs when migraine-related neurologic dysfunction produces prominent vestibular symptoms — dizziness, vertigo, motion sensitivity, and balance disruption — either alongside or instead of headache.
Many patients with vestibular migraine do not identify as "migraine sufferers" because their primary complaint is dizziness or imbalance rather than headache. This leads to years of vestibular rehabilitation that produces incomplete results, because the migraine component is never addressed.
Vestibular migraine is particularly common after concussion because the injury disrupts the same brainstem and cerebellar circuits that regulate both vestibular processing and migraine threshold. Effective treatment requires addressing both the vestibular dysfunction and the migraine component in the correct sequence.
Vestibular Migraine — Key Features
- Episodic vertigo or dizziness lasting minutes to hours
- Motion sensitivity disproportionate to vestibular findings
- Headache may be mild, absent, or follow the dizziness
- Triggered by hormonal changes, stress, sleep disruption
- Visual triggers: busy patterns, scrolling, flickering light
- Family history of migraine common
Vestibular migraine responds well to a combination of vestibular rehabilitation and migraine-specific management. Most patients see significant improvement within 8–16 weeks of correctly targeted treatment. The key is identifying the vestibular migraine component early — before years of vestibular-only rehabilitation produce incomplete results.
Is This You?
These are the patterns we hear most often from patients with persistent headache and migraine after concussion.
"I've had a headache every single day since my concussion. My neurologist says my MRI is normal."
Daily persistent headache after normal imaging"My headaches started after a car accident. They feel different from any headache I had before — pressure at the base of my skull."
New-onset cervicogenic headache pattern"I get dizzy and then the headache comes. Or the headache comes first and then I feel off-balance."
Vestibular-headache cycle"I never had migraines before my concussion. Now I get them two or three times a week."
New-onset migraine after concussion"Screens, fluorescent lights, and busy environments all trigger my headaches. I can barely work."
Sensory-triggered headache limiting function"I've tried multiple medications. They help a little but the headaches always come back."

Frequently Asked Questions
Why do I have headaches after a concussion?
Post-concussion headaches arise from disruption to the neurologic systems that regulate pain processing, sensory integration, and vascular tone. The most common drivers include cervicogenic dysfunction (neck-driven pain referred to the head), vestibular disruption (sensory mismatch triggering headache), autonomic dysregulation (abnormal blood flow and pressure regulation), and oculomotor dysfunction (eye strain from impaired tracking). Identifying which system is generating the headache determines which treatment will be effective.
What is the difference between a concussion headache and a migraine?
Post-concussion headaches and migraines share many features — throbbing pain, light and noise sensitivity, nausea — but they differ in mechanism and treatment response. Concussion headaches are driven by the neurologic disruption of the injury itself; migraines are a neurologic condition that may be triggered or worsened by concussion. Many patients develop new-onset migraine after concussion, or find that pre-existing migraine becomes more frequent and severe. A careful clinical evaluation can distinguish the primary driver and guide appropriate treatment.
How long do headaches last after a concussion?
Most post-concussion headaches resolve within 4–12 weeks with appropriate management. Headaches that persist beyond 3 months typically reflect an unaddressed neurologic constraint — most commonly cervicogenic dysfunction, vestibular disruption, or autonomic dysregulation. Persistent headache is not a sign of permanent damage; it is a signal that the primary constraint has not yet been identified and treated.
Can vestibular dysfunction cause headaches?
Yes. Vestibular dysfunction is a common driver of post-concussion headache, particularly in patients who also experience dizziness, motion sensitivity, or difficulty in visually complex environments. When the vestibular system fails to accurately process head movement, the brain compensates by increasing reliance on visual and proprioceptive input — a process that is metabolically costly and can generate headache as a downstream effect. Vestibular rehabilitation that correctly addresses the primary vestibular constraint often produces significant headache reduction.
What is vestibular migraine?
Vestibular migraine is a condition in which migraine-related neurologic dysfunction produces prominent vestibular symptoms — dizziness, vertigo, motion sensitivity, and balance disruption — in addition to or instead of headache. It is one of the most common causes of recurrent vertigo in adults and is frequently underdiagnosed. Vestibular migraine can be triggered or worsened by concussion, and it requires a different treatment approach than standard migraine or pure vestibular dysfunction.
What treatments are available for post-concussion headaches?
Effective treatment depends on identifying the primary constraint driving the headache. Cervicogenic headache responds to cervical manual therapy and neuromuscular rehabilitation. Vestibular-driven headache responds to vestibular rehabilitation. Autonomic-driven headache responds to autonomic retraining and graded aerobic exercise. Migraine-type headache may require pharmacologic support alongside rehabilitation. A constraint-based evaluation identifies which approach to prioritize, producing faster and more durable outcomes than symptom-only management.
