The Concussion Is Gone. The Migraine Machinery It Built Remains. Post-traumatic migraine (PTM) is the most common long-term consequence of concussion, affecting up to 50% of patients. In 20-30% of those cases, migraines persist beyond one year and become chronic (Lucas et al., 2014). The migraines are not caused by ongoing brain damage. The concussion activated migraine-generating pathways in the trigeminal system, cervical spine, and cortical processing networks. Once activated, these pathways sustain the migraine cycle without further injury input. If you developed migraines after a concussion and still have them years later, you have a migraine disorder with a traumatic trigger. The good news: post-traumatic migraines respond to the same interventions as other migraines, with the addition of cervical spine treatment that addresses the mechanical contribution unique to traumatic onset. Four mechanisms sustain post-traumatic migraines: Trigeminal sensitization: The trigeminal nerve became hypersensitive and fires at lower thresholds Cervicogenic input: The injured cervical spine sends pain signals through the trigeminocervical nucleus, triggering migraine cascades Cortical spreading depression: The concussion lowered the threshold for the cortical electrical wave that produces migraine aura and pain Central sensitization: The brain's pain processing volume is turned up, amplifying normal input into migraine triggers Cervicogenic Migraine Triggers: The Most Treatable Mechanism The cervical spine contribution to post-traumatic migraine is the most treatable and the most overlooked. The trigeminocervical nucleus receives sensory input from both the trigeminal nerve (face, head) and the upper cervical nerve roots (C1-C3). When the cervical spine sends pain signals into this shared nucleus, the brain cannot distinguish them from trigeminal input. The result: a cervical spine problem produces a headache indistinguishable from a neurological migraine. Treating the cervical contribution reduces migraine frequency and severity in the majority of post-traumatic migraine patients (Leslie & Bhatt, 2022). These exercises address the cervical mechanisms that lower the migraine threshold. JME 1 Cervical rotation restores upper cervical mobility lost to the protective guarding response. Restricted C1-C2 rotation increases mechanical stress on the cervical joint capsules, producing nociceptive input into the trigeminocervical nucleus. Restoring full rotation reduces this mechanical trigger input. 10 repetitions each direction, performed daily. Use slow, controlled movement. If rotation provokes migraine symptoms, reduce the range by 50% and increase gradually over weeks. JME 2 Gentle cervical stretch with chin hold strengthens the deep cervical flexors that stabilize the upper cervical spine. Weak deep flexors allow excessive motion at C1-C2 during head movements, producing the mechanical irritation that feeds migraine pathways. This exercise builds the stabilization system that prevents trigger-generating cervical dysfunction. 10 repetitions with 5-second holds. JME 4 Cervical extension addresses the loss of extension range that characterizes post-concussion cervical dysfunction. Limited extension increases load on the suboccipital muscles, which compress the greater occipital nerve at its exit point. Occipital nerve compression is a direct migraine trigger in post-traumatic patients. Restoring extension range decompresses the nerve pathway. 5-8 repetitions, gentle and controlled. JME 3 Lateral cervical flexion stretches the scalene muscles that compress the cervical nerve roots when chronically shortened. Scalene tension is nearly universal in post-concussion patients and produces referred pain patterns into the head that layer onto the migraine. Releasing scalene tension removes one layer of pain input from the trigeminocervical nucleus. 8 repetitions per side with slow breathing. Start your 14-day free trial for cervical routines that reduce migraine frequency. Thoracic Contribution to Migraine Threshold Thoracic spine stiffness forces the cervical spine to compensate, increasing migraine-triggering cervical stress. The thoracic spine should contribute 30-40% of upper body rotation. When it stiffens (from posture, desk work, or protective guarding), the cervical spine absorbs that lost rotation. The cervical spine was not designed for this additional load. The result is accelerated cervical joint stress, muscle fatigue, and nociceptive output into the trigeminocervical nucleus. JME 150 Seated thoracic rotation restores the rotation the thoracic spine should be providing. Every degree of thoracic rotation recovered is a degree of cervical stress reduced. For desk workers with post-traumatic migraines, this exercise performed every 90 minutes during the workday produces measurable reduction in afternoon migraine onset. 8 repetitions per direction. JME 153 Standing thoracic rotation provides greater range than the seated version. Perform in the evening to counteract the day's thoracic stiffness before it translates into overnight cervical compensation and morning migraine. 10 repetitions per direction with controlled breathing. JME 152 Thoracic rotation with overhead reach and visual tracking adds an upper extremity component that mobilizes the thoracic-shoulder junction where significant stiffness accumulates. The visual tracking component adds vestibular-ocular training that addresses the visual motion sensitivity common in post-traumatic migraine. 8 repetitions per side. JME 151 Lateral side bends address the lateral thoracic restrictions that limit rib cage expansion and breathing capacity. Restricted breathing reduces blood oxygen levels, and hypoxia is a documented migraine trigger. Restoring lateral thoracic mobility improves breathing mechanics and reduces the hypoxia contribution to migraine threshold. 8 repetitions per side. Reduce migraine frequency with simplmobility's targeted joint mobility programming. Lifestyle Modifications That Lower Migraine Threshold Post-traumatic migraine responds to the same threshold management as other migraines. Migraine occurs when cumulative trigger input exceeds the brain's threshold. The concussion lowered the threshold. Every trigger you remove provides more buffer before the threshold is crossed. Sleep consistency: Wake at the same time every day, including weekends. Sleep variability is the strongest modifiable migraine trigger. A 90-minute deviation from normal wake time increases migraine risk by 35-50% Hydration: Dehydration reduces cerebral blood volume. The post-concussion brain with impaired cerebrovascular reactivity is more sensitive to this reduction. Minimum 2.5 liters daily Meal timing: Blood glucose drops trigger cortical spreading depression. Eat every 3-4 hours during waking hours. Never skip breakfast Screen management: Blue light and screen flicker lower the cortical spreading depression threshold. Use blue-light filters, reduce brightness, and take screen breaks every 30 minutes Caffeine consistency: Caffeine withdrawal is a potent migraine trigger. Either consume the same amount at the same time daily or eliminate it completely. Variable caffeine intake is worse than consistent high or low intake When Medication Is Appropriate Post-traumatic migraines occurring more than 8 days per month warrant preventive medication discussion. CGRP inhibitors (gepants and monoclonal antibodies) show strong efficacy for post-traumatic migraine. Amitriptyline at low doses addresses both migraine prevention and the sleep disruption common in post-concussion syndrome. Beta-blockers address the autonomic dysregulation component. Topiramate should be used cautiously as its cognitive side effects overlap with and worsen post-concussion cognitive symptoms. Avoid medication overuse headache. Using acute migraine medications (triptans, NSAIDs) more than 10 days per month produces medication overuse headache that worsens the overall pattern. Track medication use days monthly. Are post-traumatic migraines permanent? No. Post-traumatic migraines improve or resolve in the majority of patients with appropriate treatment. The treatment must address the cervical contribution, lower the cortical excitability threshold through lifestyle management, and break the central sensitization cycle through graded exposure and appropriate medication. Patients who receive targeted multidisciplinary treatment show significant improvement within 3-6 months (Lucas et al., 2014). Do post-traumatic migraines get worse over time? Without treatment, post-traumatic migraines tend to episodically fluctuate but do not progressively worsen in terms of the underlying pathology. They get functionally worse through medication overuse headache, progressive deconditioning, and expanding avoidance behaviors. With treatment targeting the cervical spine, autonomic regulation, and threshold management, the trajectory reverses toward improvement. Should I see a neurologist or a concussion specialist for post-traumatic migraines? Both. A neurologist provides migraine-specific medication management and rules out other headache pathologies. A concussion specialist or physiotherapist addresses the cervical spine contribution and autonomic dysregulation that neurological treatment alone misses. The combination produces better outcomes than either specialist alone. References Lucas, S., et al. (2014). Prevalence and characterization of headache following mild traumatic brain injury.
