The Headache That Begins in the Neck

You've tried the dark room, the ice pack, the over-the-counter medication. Nothing touches it, because the problem was never behind your eyes to begin with. Most headaches aren't actually head problems. The top three joints in the neck share a nerve pathway with the trigeminal nerve, the same nerve responsible for most facial and head sensation, at a junction in the brainstem called the trigemino-cervical nucleus. When a joint at the base of the skull loses its normal motion, the nervous system can misread that signal as pain behind the eye, across the temple, or wrapped around the back of the head. The head hurts. The neck is where the problem actually lives.

This is the mechanism behind cervicogenic headache: pain that starts in the neck but is felt in the head, typically on one side, often worse after long hours at a screen, and usually paired with tightness in the muscles at the base of the skull. Tension-type headaches can involve a similar contributing pattern, though their causes are broader and less singular. Even in patients with a formal migraine diagnosis, neck dysfunction is a well-documented trigger, not the underlying disease itself, an important distinction, since treating the trigger and treating the condition are two different things. That distinction matters more than it sounds like it should. The official medical classification system for headache disorders lists more than 150 distinct types, which is part of why "I have a headache" is really the start of a question, not the end of one.

Assessment matters more than the label. We examine cervical range of motion, the flexion-rotation test for C1–C2 restriction, palpation of the suboccipitals and upper trapezius, jaw mechanics, breathing pattern and the position the head is held in during the working day. Headaches that reproduce with palpation of the upper neck have a mechanical source worth treating.

Getting this right starts with a real assessment, not a guess. We check range of motion in the neck, use a specific test for restriction at the very top of the spine, feel for tightness in the muscles at the base of the skull and across the upper shoulders, and look at jaw mechanics, breathing pattern, and how the head sits during a normal workday. When pressing on the upper neck reproduces the familiar headache, that's a strong signal the source is mechanical rather than something else entirely.

Care from there is conservative and specific: precise adjustments to the neck and upper back to restore normal joint motion, soft tissue work through the tightest muscle groups, and retraining the deep neck muscles so the correction actually holds instead of drifting back. A body of clinical research supports manual therapy and spinal adjustment specifically for cervicogenic and tension-type headache. What we don't do is treat headaches indefinitely without asking why they're happening. Certain warning signs, a sudden and severe onset, any new neurological change, a headache paired with fever, are referred out immediately, no exceptions. Everything else tends to respond well to an accurate diagnosis, a focused course of care, and a workstation that stops recreating the same problem every single morning.
