Headache After Concussion: 6 Patterns and What Helps

Headache after concussion is common, but “post-concussion headache” is not one tidy diagnosis with one treatment. It is a timing label first: the headache started after a blow, fall, crash, sports impact, whiplash, or other head and neck trauma. The pain itself may look like migraine, tension-type headache, neck-referred pain, eye strain, vestibular overload, medication overuse, exertion intolerance, or a mixed pattern.

That distinction matters. The person whose headache spikes after grocery-store aisles and scrolling may need a different plan than the person whose pain starts at the base of the skull after neck rotation. The person taking pain medicine most days may need medication guidance before adding more exercises. The person with a worsening headache and repeated vomiting needs urgent medical care, not a home rehab routine.

Use this guide as a vocabulary builder for your next medical or therapy visit. It is not a self-diagnosis tool.

First: Headache Red Flags After a Head Injury

Seek emergency care or call local emergency services after a head injury if headache comes with any CDC danger signs:

• A headache that gets worse and does not go away
• Repeated vomiting
• Weakness, numbness, decreased coordination, convulsions, or seizures
• Slurred speech or unusual behavior
• One pupil larger than the other
• Severe confusion, agitation, inability to recognize people or places, loss of consciousness, extreme drowsiness, or inability to wake up

Do not try to “treat through” those symptoms with screens, exercise, vestibular drills, pain medicine, or sleep. They need urgent assessment.

What Type of Headache Is Common After Concussion?

Post-traumatic headaches often resemble migraine or tension-type headaches. The International Classification of Headache Disorders also classifies headache after head or neck trauma as a secondary headache: it is attributed to the injury when the timing fits, even if the pain has migraine-like or tension-type features.

The practical takeaway:

• Migraine-like symptoms point toward headache-specific medical management and trigger control.
• Tension or neck-linked symptoms point toward cervical and musculoskeletal assessment.
• Eye, screen, or motion-triggered symptoms point toward vestibular, oculomotor, or vision assessment.
• Daily headaches with frequent medication use raise the question of medication-overuse headache.
• Exercise-triggered headaches may involve exertion intolerance, autonomic regulation, migraine biology, or neck load.

Most real cases are not pure. A patient can have migraine-like headache plus neck pain plus screen-triggered dizziness. That is why the useful question is not only “What type is it?” It is “What pattern shows up reliably, and what changes it?”

Why a Headache Can Persist for Months

The ICHD-3 classifies post-traumatic headache as acute during the first 3 months and persistent when it continues beyond that window. That does not mean the pain is untreatable after 3 months. It means the headache deserves a more specific look at the systems that may be keeping it active.

Common contributors include:

• A pre-existing migraine tendency that became more frequent after the injury
• Neck or jaw injury from the same impact or whiplash motion
• Visual strain from convergence, focusing, smooth pursuit, or saccade problems
• Vestibular-ocular mismatch, where head motion, eye tracking, and balance signals do not integrate cleanly
• Poor sleep, anxiety, depression, PTSD symptoms, deconditioning, or high daily stress load
• Frequent use of acute pain medication
• Returning to full work, school, driving, sport, or screen exposure before symptoms can tolerate it

Persistent headache should not be dismissed as “just concussion.” It also should not be treated as proof of permanent damage. The next step is pattern-specific assessment.

Pattern 1: Migraine-Like Headache After Concussion

This headache often feels throbbing or pulsing. It may be one-sided, but it can also be bilateral. It may come with nausea, light sensitivity, sound sensitivity, dizziness, motion sensitivity, or needing to lie down in a quiet room. Routine activity can make it worse.

What may be driving it:

• The injury may have triggered migraine biology in someone with or without a known migraine history.
• Sleep disruption, stress, skipped meals, dehydration, bright light, noise, screens, neck pain, and exertion can lower the threshold.
• Vestibular and visual symptoms can amplify the headache, especially in busy environments.

What usually helps:

• Get medical guidance early instead of escalating over-the-counter medication on your own.
• Track attack timing, suspected triggers, medication use, nausea, light sensitivity, sound sensitivity, dizziness, and recovery time.
• Ask whether the headache pattern should be treated like migraine, tension-type headache, or a mixed post-traumatic headache phenotype.
• Reduce avoidable triggers temporarily, then rebuild tolerance. Long-term total avoidance can shrink activity tolerance.

Risky assumption: “It cannot be migraine because it started after a concussion.”

Post-traumatic headache can have migraine-like features. The timing links it to the injury; the symptom pattern still matters for treatment.

Pattern 2: Tension-Type Pressure and Muscle Guarding

This headache often feels like pressure, tightness, or a band around the head. It may be on both sides. Neck, scalp, jaw, or shoulder muscles may feel tender. The pain may build as the day goes on, especially with desk work, stress, poor sleep, or guarded posture.

What may be driving it:

• The same incident that caused the concussion may have strained the neck, jaw, upper back, or shoulder girdle.
• After injury, people often hold the head and shoulders stiffly to avoid dizziness or pain.
• Stress and poor sleep can raise muscle tone and lower the pain threshold.

What usually helps:

• A clinician should screen the neck and jaw when headache is tied to muscle tenderness, posture, or neck movement.
• Gentle heat, short movement breaks, breathing exercises, and light neck or shoulder mobility may help if they do not flare symptoms.
• Physical therapy, massage therapy, or other manual approaches may be useful when matched to the exam.
• Medication should be used according to a clinician’s plan, especially if headaches are frequent.

Illustrative example: if your headache is mild in the morning, rises after 3 hours at a laptop, and feels better after lying down with neck heat, the useful clinical clue is not simply “screen headache.” It may be a combined visual, posture, and neck-load problem.

Pattern 3: Cervicogenic Headache After Concussion or Whiplash

Cervicogenic headache means pain is referred from the neck. It often starts near the base of the skull, behind one ear, or in the upper neck, then spreads toward the temple, forehead, or eye. Neck rotation, extension, sustained posture, or pressure on tender upper-neck tissues may reproduce it.

What may be driving it:

• A concussion mechanism can also be a whiplash mechanism.
• Upper cervical joints, muscles, ligaments, and nerves share pain pathways with the head.
• Neck position signals also interact with vestibular and visual systems, so neck-driven headache can travel with dizziness or visual symptoms.

What usually helps:

• Ask for a cervical spine and musculoskeletal exam if headache changes with neck movement or position.
• Treatment may include graded neck mobility, strengthening, postural load management, manual therapy, and vestibular work when dizziness or gaze instability is also present.
• Avoid aggressive self-manipulation after head and neck trauma unless a qualified clinician has assessed you.

Risky assumption: “A normal head scan means my neck cannot be part of the headache.”

Head imaging does not rule out a cervical driver. Many post-concussion headache plans miss the neck because the patient leads with “concussion” instead of “the headache starts at my upper neck when I turn right.”

Pattern 4: Vestibular or Ocular-Triggered Headache

This headache shows up behind the eyes, in the forehead, at the temples, or as a pressure sensation that builds with visual or motion demand. Common triggers include reading, screens, scrolling, quick head turns, driving, grocery stores, patterned floors, crowds, or bright busy environments.

What may be driving it:

• The vestibular-ocular reflex, or VOR, helps keep vision stable while the head moves.
• After concussion, gaze stabilization, convergence, focusing, saccades, smooth pursuits, or visual motion tolerance may be impaired.
• The brain has to spend more effort matching eye, inner-ear, neck, and posture signals. Headache can be the cost of that extra work.

What usually helps:

• Ask for vestibular and vision screening if headache appears with dizziness, blurred vision, double vision, eye strain, motion sensitivity, or busy-environment overload.
• Rehab may include gaze-stabilization exercises, smooth pursuit and saccade training, convergence work, balance tasks, and graded visual motion exposure.
• Dose matters. A drill that causes a small, brief symptom rise may be useful. A drill that causes a headache for the rest of the day is probably too much.

Labeled example: a screen-triggered headache can have different drivers.

• Brightness-driven pattern: the headache starts quickly under glare or LED light, even with static text.
• Near-work pattern: the headache builds after reading or focusing up close.
• Motion-driven pattern: the headache spikes with scrolling, video, games, or busy visual scenes.
• Head-movement pattern: the headache appears when the head moves while the eyes try to stay locked on a target.

The same laptop can trigger all four, but the treatment emphasis may differ.

Pattern 5: Medication-Overuse or Rebound Headache

Medication-overuse headache is not a character flaw and it does not mean the original pain was imaginary. It can happen when acute headache medication is used frequently enough that the medication pattern starts helping maintain the headache cycle.

It may feel like a near-daily headache, a headache that returns as medicine wears off, or a pattern where more medication is needed for less relief. It can involve over-the-counter pain relievers, combination products, prescription migraine medicines, or other acute headache medications.

What may be driving it:

• The nervous system adapts to frequent acute medication exposure.
• The original post-traumatic headache remains active, so the person keeps treating it.
• Without a prevention or rehab plan, the only available tool becomes repeated rescue medication.

What usually helps:

• Do not abruptly change prescription medication without medical guidance.
• Track medication days, dose, headache severity, and what happens when medication wears off.
• Ask your clinician directly: “Could medication overuse be contributing to this pattern?”
• The plan may involve changing the acute medication strategy, adding preventive treatment, treating neck or vestibular contributors, and using non-medication supports during the transition.

The Living Concussion Guidelines specifically warn that frequent acute medication use can perpetuate post-traumatic headache, and they recommend clear instructions about safe dosing and monthly frequency.

Pattern 6: Exertional or Autonomic Headache

This headache appears during or after activity: brisk walking, stairs, running, lifting, sport drills, heat exposure, sex, straining, or a busy workday that combines standing, talking, screens, and movement. It may come with lightheadedness, nausea, racing heart, dizziness, fatigue, or a “crash” later in the day.

What may be driving it:

• The brain and body may not yet tolerate the same heart-rate, blood-flow, heat, or sensory demand as before the injury.
• Migraine physiology, neck load, dehydration, poor sleep, and deconditioning can all lower the exertion threshold.
• Some people need a graded aerobic plan rather than a direct return to full workouts.

What usually helps:

• Get checked if exertion causes severe, sudden, unusual, or worsening headache.
• Use a graduated return-to-activity plan rather than repeated boom-and-bust attempts.
• Many concussion programs use sub-symptom-threshold aerobic exercise: activity below the level that causes a major symptom flare, progressed over time.
• Track the trigger threshold: type of activity, duration, intensity, heart rate if available, peak headache, and recovery time.

Risky assumption: “If exercise is healthy, pushing harder will speed recovery.”

Exercise often belongs in recovery, but the dose has to match the current threshold. A plan that is too aggressive can make the headache pattern harder to read.

A Headache Diary That Is Actually Useful

Generic tracking often says, “Headache again.” That is not enough information to guide care.

Track these details for 1 to 2 weeks:

• Time of onset and duration
• Pain location: forehead, temples, behind eyes, one side, both sides, base of skull, neck
• Pain quality: pressure, pulsing, sharp, burning, stabbing, tight, electric, heavy
• Associated symptoms: nausea, light sensitivity, sound sensitivity, dizziness, blurred vision, double vision, brain fog, neck pain, jaw pain
• Triggers: screens, reading, scrolling, driving, head turns, exercise, poor sleep, stress, meals, hydration, bright light, noise, busy places
• Medication: name, dose, time taken, and whether the headache returns when it wears off
• Recovery: what helped, what worsened it, and how long it took to settle

Bring that diary to your clinician. It helps distinguish migraine-like headache from cervical, vestibular, ocular, exertional, or medication-overuse patterns.

When to Ask for a More Specific Assessment

Follow up with a healthcare professional within a few days after a concussion, especially if symptoms are not clearly improving. Ask for reassessment sooner if headaches worsen, become unsafe, or interfere with work, school, driving, sleep, or basic daily function.

Depending on the pattern, the right evaluation may include:

• A neurological exam and review of red flags
• A medication review and headache diagnosis
• A cervical spine, jaw, and musculoskeletal exam
• Vestibular and balance testing
• Vision, binocular vision, convergence, focusing, and eye-movement screening
• Sleep, mood, exertion tolerance, hydration, and autonomic review
• Referral to a headache specialist, neurologist, vestibular physical therapist, concussion clinic, neuro-optometrist, optometrist experienced with concussion, ophthalmologist, or other qualified clinician

If vestibular, vision, balance, or coordination symptoms remain functionally limiting beyond 1 month, the Living Concussion Guidelines recommend assessment by a healthcare professional with specialized training in the vision or vestibular system.

How Post-Concussion Headaches Are Treated

The best treatment is not “one headache remedy.” It is matching treatment to pattern.

If the pattern is migraine-like

Talk with a clinician about acute and preventive options, light and sound management, sleep, hydration, meals, gradual activity, and whether other concussion symptoms are feeding the headache.

If the pattern is tension or neck-driven

Ask for cervical, jaw, posture, and musculoskeletal assessment. Treatment may involve physical therapy, gentle mobility, strengthening, manual therapy, ergonomic changes, and load management.

If the pattern is vestibular or ocular

Ask whether vestibular rehabilitation or vision therapy is appropriate. Exercises may include VOR x1 or x2, smooth pursuits, saccades, convergence, balance progression, and graded exposure to visual motion.

If the pattern suggests medication overuse

Bring a medication diary. Ask for a plan that covers both the underlying headache and the medication cycle. Do not try to solve frequent headaches by simply adding more rescue medication.

If the pattern is exertional

Ask about graded return to activity and sub-symptom-threshold aerobic exercise. The goal is to expand tolerance without repeatedly provoking a large flare.

How EyeRehab Fits In

EyeRehab is most relevant when headaches travel with eye strain, dizziness, gaze instability, screen intolerance, busy-environment symptoms, or head-motion triggers. Those patterns often need structured, measurable practice rather than random eye exercises.

The app can support:

• VOR x1 and VOR x2 gaze-stabilization practice
• Smooth pursuit, saccade, and convergence exercises
• Symptom tracking before and after exercises
• Consistent home practice between clinical visits

It should not replace medical assessment after a head injury. Use your clinician’s plan as the source of truth when you have one. If symptoms are severe, worsening, unusual, or not yet assessed, get checked before starting or progressing home vestibular or vision exercises.

Key Takeaways

• Headache after concussion is a timing label first. The pain pattern may resemble migraine, tension-type headache, cervicogenic headache, vestibular or ocular overload, medication overuse, exertion intolerance, or a mix.
• Red flags such as worsening headache that does not go away, repeated vomiting, seizures, weakness, slurred speech, unequal pupils, severe confusion, or inability to wake need urgent care.
• Persistent headache does not always mean permanent injury. It often means the driver has not been identified yet.
• A headache diary should capture triggers, location, pain quality, associated symptoms, medication days, and recovery time.
• VOR and visual exercises are most relevant when headache is tied to head movement, gaze instability, screens, reading, dizziness, or busy visual environments.
• The safest recovery plan matches treatment to the pattern and escalates care when symptoms are worsening, unsafe, or not improving.
