Understanding Headaches After Concussion

Experiencing a headache with eye exercises during concussion recovery can be discouraging, but it is a highly common and expected part of the healing process. Headaches after concussion are one of the most frequently reported symptoms, and because visual and vestibular rehabilitation directly challenges an injured brain, triggering mild symptom flare-ups is normal. Understanding why this happens, how to manage it, and when to seek medical advice will help you navigate your recovery safely and effectively.

Why can eye exercises trigger headache after concussion?

Eye exercises trigger headaches after a concussion because they force the injured brain to process complex visual and vestibular signals simultaneously, temporarily overwhelming fatigued neural pathways.

After a head injury, the brain’s energy demands increase as it works to heal, but its actual energy supply is often reduced. This creates an “energy crisis.” The vestibulo-ocular reflex (VOR)—which keeps your vision stable and prevents dizziness when your head moves—relies on seamless communication between your eyes, inner ear, and brain.

When you perform VOR training, saccades, or smooth pursuit exercises, you are directly asking an injured, fatigued brain to work overtime. This increased neurological workload often results in a headache with eye exercises, as the brain struggles to keep up with the visual demands.

Types of Post Concussion Headaches

Not all headaches are the same. Identifying the type of pain you are experiencing can help you and your healthcare provider manage it more effectively. Common types include:

• Cervicogenic Headache (Concussion): Pain that originates from the neck. A concussion often involves a whiplash mechanism, injuring the cervical spine. The nerves in the upper neck share connections with the brain’s pain centers, causing pain that radiates up the back of the head and behind the eyes.
• Concussion Migraine: Characterized by moderate to severe throbbing pain, often on one side of the head. This can be accompanied by sensitivity to light and sound, nausea, or visual auras.
• Tension-Type Headaches: Often described as a tight band of pressure around the head. This can be triggered by the physical and mental stress of recovery, or from tensing neck and shoulder muscles during visual exercises.
• Oculomotor Headaches: Directly caused by visual strain. When the muscles controlling eye movement fatigue during convergence or tracking exercises, it results in pain localized around the eyes, forehead, or temples.

How much symptom increase is acceptable during rehab?

An acceptable symptom increase during rehab is generally considered a mild exacerbation of no more than 2 points on a 10-point scale during the exercise, which resolves shortly after stopping the activity.

In vestibular and concussion rehabilitation, the goal is to “challenge but not overwhelm” the brain. You must expose the brain to the stimuli that cause symptoms (like head movement or visual tracking) to promote neuroplasticity and recovery, a concept known as graded exposure.

If your baseline headache is a 2 out of 10, pushing it to a 4 or 5 during VOR training is an acceptable, productive challenge. However, if the pain spikes to an 8 or 9, or if you experience severe dizziness and nausea, you have pushed too far. A acceptable symptom flare-up should return to its baseline level within 15 to 30 minutes of resting in a quiet, dimly lit room. If symptoms remain elevated for hours or days, the exercise was too aggressive.

What is “Normal” vs. Concerning During Vestibular Therapy?

It is entirely normal to experience mild discomfort when progressing through your rehabilitation. However, knowing the difference between productive fatigue and concerning pain is vital for your safety.

What is considered normal:

• A mild to moderate increase in head pain during the exercise.
• Mild eye strain or fatigue.
• A temporary feeling of motion sensitivity or slight unsteadiness.
• Symptoms that calm down relatively quickly once you rest your eyes.

What is considered concerning (and requires pausing your exercises):

• Severe, sudden, or abrupt headaches.
• Pain that does not improve with rest.
• Worsening visual disturbances, such as double vision (diplopia) or loss of peripheral vision.
• The onset of neurological symptoms like numbness, tingling, or severe confusion.

When should post-concussion headaches be checked?

Post-concussion headaches should be checked by a healthcare professional immediately if they rapidly worsen, are severe, or are accompanied by “red flag” symptoms like worsening confusion, slurred speech, weakness, or changes in consciousness.

According to the CDC, you should seek urgent medical care if your headache gets worse and simply will not go away, or if you experience repeated vomiting, convulsions, or an inability to wake up. These could be signs of a more serious brain injury, such as a bleed, requiring immediate intervention.

Additionally, you should consult your doctor or vestibular therapist if your post concussion headaches are not gradually improving over time, or if you consistently experience severe headaches with eye exercises despite resting appropriately. A specialist can evaluate your cervical spine, visual system, and vestibular function to ensure you are on the right treatment path.

Tips for Managing Headaches With Eye Exercises

If you are struggling with symptom flare-ups during your visual rehab, these strategies can help keep your recovery on track:

1. Pace Yourself: Break your exercises into shorter, more frequent sessions. Doing three 5-minute sessions is often better tolerated than one 15-minute session.
2. Optimize Your Environment: Perform exercises in a well-lit room to reduce eye strain. Avoid complex visual backgrounds (like patterned carpets or bright screens) while doing VOR exercises.
3. Monitor Your Neck: If you suspect a cervicogenic headache concussion is contributing to your pain, ensure your neck is relaxed. Poor posture or tense neck muscles during eye training will compound your headaches.
4. Track Your Symptoms: Use a daily symptom tracker to monitor your triggers. Logging your dizziness, brain fog, and headache levels before and after exercises helps you find your “sweet spot” for difficulty progression.

Key Takeaways

• Headaches after concussion are highly common, particularly when performing visual and vestibular rehabilitation exercises.
• Eye exercises trigger headaches by demanding an injured, fatigued brain to process complex visual and movement signals.
• An acceptable symptom increase during rehab is typically a mild exacerbation (no more than 2 points on a 10-point scale) that resolves within 30 minutes of resting.
• “Red flag” symptoms—like a sudden, severe worsening headache, weakness, numbness, or confusion—require immediate emergency medical evaluation.
• Recovery requires balance. It is important to challenge the brain to promote healing, but pushing through severe pain can set back your recovery.
