Not every headache starts in the head. Some begin in the neck and travel upward, a pattern called a cervicogenic headache. Because the pain is felt in the skull, behind the eye, or at the temple, many people spend years treating "headaches" without anyone examining the structure that's actually generating them: the cervical spine.
What is a cervicogenic headache?
A cervicogenic headache is referred pain. The upper joints, discs, and soft tissues of the neck share nerve pathways with regions of the head, so irritation in the neck can be perceived as pain in the head. In other words, the head hurts, but the neck is the source. This is a recognized headache classification, not a fringe theory. It matters because a headache that originates in the neck often responds better to treatment aimed at the neck than to approaches that only address the symptom.
How it differs from tension headaches and migraines
Cervicogenic headaches have a few telltale features that help distinguish them from other types:
- Usually one-sided. The pain typically stays on the same side of the head and doesn't switch sides the way migraines sometimes do.
- Starts at the neck or base of the skull. The pain tends to begin low and spread upward toward the temple, forehead, or behind the eye.
- Triggered or worsened by neck movement. Turning the head, holding one position too long, or pressure on certain neck joints can set it off, which is rarely true of migraines.
- Often comes with neck stiffness or reduced motion on the painful side.
Tension headaches, by contrast, usually feel like a band of pressure on both sides, and migraines often bring nausea, light sensitivity, or visual changes. The categories can overlap, which is one reason a careful history and exam matter more than self-diagnosis. If headaches are frequent, severe, or different from anything you've had before, discuss them with a healthcare provider.
Common causes
Several issues in the cervical spine can refer pain into the head. Joint dysfunction in the upper neck (segments that have become restricted or irritated) is among the most common findings. Sustained forward-head posture from desk work and phone use loads those same joints hour after hour. Old injuries play a role too: whiplash from a car accident, even one that happened years ago, can leave behind joint and soft-tissue changes that surface later as recurring headaches. We cover this relationship in more depth in our post on the connection between neck problems and headaches.
Headaches after a car accident deserve prompt attention. Head pain that develops in the days or weeks after a collision often traces to the neck. An evaluation can identify whether cervical injury is the source. See our full range of services for how we approach it.
How an evaluation finds the source
At Physical Medicine Health Center, the goal of the first visit is identification, not assumption. We take a detailed headache history (where the pain starts, which side, what triggers it), then examine neck motion, joint function, and muscle tension. When the exam indicates it, we take X-rays in-house to look at the alignment and condition of the cervical spine. If the findings don't point to the neck, we say so, and we'll recommend the type of provider who is a better fit.
Conservative treatment approaches
When the neck is the source, cervicogenic headaches often respond well to conservative care. Depending on the exam findings, a plan may include chiropractic adjustments to restore motion in restricted joints, targeted soft-tissue work, posture correction, and specific exercises to strengthen the deep neck muscles. The aim is to reduce both the intensity and the frequency of headaches over time by treating the structure generating them, and to give you tools to keep them from returning. Results vary from person to person, which is why care is planned around your exam rather than a one-size-fits-all protocol.
Key takeaway: A one-sided headache that starts at the neck and worsens with neck movement may be cervicogenic: referred pain from the cervical spine. A focused exam can identify the source, and conservative care directed at the neck often helps.
