Different Headache Locations Reflect Different Pain Generators A concussion headache that changes location is not random. Each location points to a specific pain mechanism. Post-concussion headache involves at least four distinct pain generators: cervicogenic (from the upper cervical spine), vascular/autonomic (from disrupted blood flow regulation), tension-type (from sustained muscle contraction), and migraine-type (from cortical spreading depolarization). These systems activate at different times and in different combinations during recovery (Ashina et al., 2021). Frontal headache in early recovery typically reflects autonomic dysfunction. The concussive impact disrupts cerebral blood flow autoregulation. The frontal lobes receive blood through the anterior cerebral artery, which is sensitive to autonomic changes. When blood flow regulation is impaired, the frontal region experiences vascular headache. This is why frontal headache worsens with cognitive effort, screen use, and upright posture, all of which increase frontal lobe metabolic demand. Cervicogenic referral also produces frontal headache. The C1-C3 spinal segments share neural pathways with the trigeminal nerve through the trigeminocervical nucleus. Dysfunction in the upper cervical spine refers pain to the forehead, temples, and behind the eyes. The whiplash component of concussion injures the upper cervical joints and muscles, creating cervicogenic headache that overlaps with the autonomic headache in the frontal region. Why the Headache Shifts to the Top of the Head Vertex (top of head) headache signals a transition to tension-type and muscular pain generators. As the autonomic system recovers and vascular headache improves, the muscular tension pattern becomes the dominant pain source. The suboccipital muscles, upper trapezius, and temporalis muscles develop sustained contraction from weeks of guarding and protective posturing. These muscles refer pain to the vertex through the greater occipital nerve (C2 dorsal ramus) and the third occipital nerve (C3 dorsal ramus) (Fernandez-de-las-Penas et al., 2020). Prolonged screen avoidance and reduced activity worsen the muscular component. When patients restrict activity and spend extended time in recumbent positions, the cervical stabilizers weaken and the superficial neck muscles compensate. This compensation pattern shifts the headache from the frontal vascular pattern to the vertex tension pattern. The headache location change is a sign that recovery is progressing but the cervical component needs direct treatment. The shift also reflects central sensitization. After weeks of persistent headache, the trigeminal pain processing system becomes sensitized. Lower-intensity signals from the cervical muscles now produce headache when the same signals would not have been painful before the concussion. The vertex location reflects the convergence zone where cervical afferents meet trigeminal processing in the brainstem. Exercises to Address Frontal Headache Drivers JME 155 Diaphragmatic breathing directly addresses the autonomic dysfunction driving frontal headache. The 4-second inhale, 6-second exhale pattern shifts the autonomic nervous system toward parasympathetic dominance, improving cerebral blood flow regulation. For frontal headache, perform this exercise at the first sign of headache onset. 10 breaths, performed 4-5 times daily and as needed when frontal headache increases. JME 14 Chin tucks address the cervicogenic component of frontal headache by retraining the deep cervical flexors. When these muscles are weak (which occurs after every concussion due to the whiplash mechanism), the upper cervical joints become hypermobile and irritable, referring pain to the forehead and behind the eyes. 10 repetitions with 5-second holds, 3 times daily. JME 1 Cervical rotation recalibrates the proprioceptive system in the upper cervical spine. Impaired proprioception contributes to both the cervicogenic headache component and the dizziness that often accompanies frontal headache after concussion. Slow, controlled rotation (3 seconds each direction) within the pain-free range. 10 repetitions each direction. JME 150 Seated thoracic rotation reduces the thoracic stiffness that forces the cervical spine to compensate. When the thoracic spine is stiff, the upper cervical segments must provide extra rotation, increasing the irritation that drives cervicogenic frontal headache. Restoring thoracic mobility reduces cervical load. 8 repetitions per direction. Start your 3-day free trial for targeted concussion headache programming. Exercises to Address Vertex Headache Drivers JME 3 Lateral cervical flexion releases the scalene and upper trapezius tension that refers pain to the vertex. The upper trapezius trigger point referral pattern matches the vertex headache location. Gentle lateral flexion with sustained holds (15-20 seconds) reduces the muscular tension driving the top-of-head pain. 8 repetitions per side. JME 42 Shoulder circles break the shoulder elevation pattern that sustains upper trapezius tension. The protective shoulder posture after concussion creates a self-reinforcing cycle: elevated shoulders increase upper trapezius tension, which refers pain to the vertex, which causes more guarding, which elevates the shoulders further. Shoulder circles interrupt this cycle. 10 repetitions each direction, multiple times daily. JME 15 Cervical extension addresses the suboccipital compression that contributes to vertex headache via the greater occipital nerve. The suboccipital muscles compress the greater occipital nerve when the cervical spine is held in sustained flexion (the common "looking down" posture of concussion recovery). Gentle extension decompresses the nerve. 8 repetitions, slow and controlled. JME 151 Lateral side bends with breathing address both the muscular tension and autonomic components simultaneously. The lateral movement stretches the quadratus lumborum and lateral trunk muscles while the breathing pattern maintains parasympathetic tone. For patients whose headache has shifted from frontal to vertex, this combination exercise addresses the transition between pain generators. 8 repetitions per side. Address your specific headache pattern with simplmobility's concussion recovery programming. When to Seek Additional Evaluation Headache location changes are normal during concussion recovery, but certain patterns warrant evaluation. A headache that is strictly one-sided and never shifts should be evaluated for cervical artery dissection (rare but important). A headache that suddenly becomes the "worst headache of your life" requires emergency evaluation. A headache that changes character from dull to thunderclap requires imaging. If the vertex headache persists beyond 4-6 weeks, request cervical spine assessment. Many providers treat post-concussion headache as a brain problem when the pain generator has shifted to the cervical spine. A physiotherapist trained in cervical assessment (manual palpation of C1-C3 segments, flexion-rotation test, cervical proprioception testing) identifies the cervical contribution that targeted treatment addresses. Occipital nerve blocks provide diagnostic and therapeutic value. If vertex headache responds to a greater occipital nerve block, the pain generator is confirmed as cervical/occipital. This diagnostic information guides treatment: cervical rehabilitation and occipital nerve management rather than concussion-specific brain rest. Common Mistakes Treating all post-concussion headaches the same regardless of location. A frontal autonomic headache responds to rest and autonomic regulation. A vertex tension headache responds to cervical rehabilitation and muscle release. Using rest for a tension headache or exercise for an acute autonomic headache produces poor outcomes. Assuming the headache shift means the concussion is getting worse. The location change typically reflects recovery progression, not deterioration. The autonomic system is improving (reducing frontal headache) while the muscular/cervical component becomes more apparent. Ignoring the cervical spine. Up to 50% of persistent post-concussion headache has a cervicogenic component. If the headache has shifted to the vertex and been present for weeks, the cervical spine is the most likely primary pain generator. Is it normal for concussion headaches to move around? Yes. Headache location changes reflect different pain generators activating at different recovery stages. Frontal headache early in recovery shifting to vertex headache later is the most common pattern and typically indicates the autonomic system is recovering while muscular tension remains. Does the headache location tell me which treatment to use? Yes. Frontal headache responds best to autonomic regulation (breathing exercises, graded aerobic exercise, screen management). Vertex headache responds best to cervical rehabilitation (chin tucks, cervical stretching, manual therapy). Most patients benefit from both approaches at different recovery stages. When should I worry about a headache that changes location? Seek emergency evaluation for sudden thunderclap headache, strictly one-sided headache that never shifts (evaluate for vascular causes), or headache with new neurological symptoms (vision loss, weakness, speech changes). Gradual headache migration between regions during recovery is expected and not concerning. References Ashina, H., et al. (2021).
