Migraine involves abnormal activity in the trigeminovascular system, where the trigeminal nerve, blood vessels, and brainstem interact to produce pain, sensory sensitivity, and nausea. Genetics, hormonal shifts, sleep disruption, and dietary triggers can all lower the threshold at which an attack begins. The American Migraine Foundation describes migraine as a whole-body neurological disease, not just a bad headache.
Tension headache is driven by sustained contraction of the suboccipital, upper trapezius, and cervical paraspinal muscles, often from forward head posture, prolonged screen time, jaw clenching, or stress. Trigger points in these muscles refer pain into the temples, forehead, and behind the eyes, closely mimicking migraine.
What is often missed is how cervical dysfunction, myofascial tension, and cranial strain can act as ongoing triggers for BOTH conditions. Restriction at the upper cervical joints (C1-C2) sensitizes the trigeminocervical nucleus, which is why gentle work on the neck can quiet migraine as well as tension headache. Addressing these structural inputs with myofascial release and muscle energy technique often reduces both frequency and severity.
