When the Headache Starts in Your Neck: Occipital Neuralgia, Cervicogenic Headache, and the Test That Comes Closest to an Answer

What this video covers

• How upper neck nerves meet the face nerve’s fibers and send pain to the eye, temple and forehead
• The workup that tells occipital neuralgia, cervicogenic headache and migraine apart
• Why a diagnostic block answers a question before it treats anything
• What the randomized data on occipital nerve blocks really shows, and what it does not. The trial followed patients for only two weeks, so it tells us nothing about lasting relief. A plain numbing block lasts hours to a day or two. It is mainly a diagnostic test. Adding a steroid may stretch that to weeks in some patients, on weaker evidence
• Third occipital nerve radiofrequency neurotomy: 43 of 49 patients had complete relief lasting at least 90 days, median 297 days. That came from one center’s uncontrolled series, run by the group that invented the technique. And it was only in patients whose diagnosis was first confirmed by controlled comparative diagnostic blocks
• Key risks and expected effects. After third occipital nerve neurotomy, most patients get unsteadiness and ataxia (loss of balance), and about half get scalp numbness. A small share get painful post-neurotomy neuralgia (nerve pain after the neurotomy). Other risks: bleeding, infection, fainting (vasovagal reaction), allergic reaction, injection into a blood vessel with numbing-drug toxicity, and no relief at all. With a steroid, add high blood sugar plus hair loss, skin thinning and skin lightening at the injection site

A headache that starts in the neck comes from the upper cervical nerves and joints, not the brain. The C1 to C3 nerve fibers share a relay with the trigeminal nerve, the nerve that serves the face. So a sore neck structure is felt at the temple and behind the eye. Occipital neuralgia and cervicogenic headache are sorted out with a diagnostic block, not another migraine preventive.

It begins at the base of your skull, on one side, always the same side. A deep, boring ache sits under the occiput (the bony bump at the back of the head). It climbs over the back of your head, wraps the temple, and settles behind the eye. Turning to check a blind spot sets it off. Sleeping wrong sets it off for two days. You have been told it is migraine. Triptans, preventives, a neurologist, a normal brain MRI, a shrug. This article lays out another option. Head pain that starts in the neck is not a kind of migraine, and it is diagnosed a different way.

How can a neck problem cause a headache?

The anatomy explains this. Learn it before anyone offers you a fourth preventive.

The sensing fibers of the first three neck nerves, C1, C2, and C3, enter the upper cervical dorsal horn. That is the first relay station in the spinal cord at the top of the neck. It runs straight into the descending trigeminal nucleus, the relay that carries feeling from your face, your eye, and your forehead. Neck and face fibers meet on the same next-in-line nerve cells. That meeting point is called the trigeminocervical nucleus.

In other words, two very different areas report to the same switchboard. Animal nerve studies and human pain mapping back this up. It best explains why a sore structure at the back of your neck causes pain at the eye socket, the temple, and the top of the head. That is the mechanism, stated at its real strength. It is a well-supported explanation, not a bedside test anyone runs on you.

The specific structures that feed that line

Four named structures feed into that shared relay, and any of them can be the source:

• The greater occipital nerve, which comes off the C2 dorsal ramus (a nerve branch at the back of the spine).
• The lesser occipital nerve, from the cervical plexus.
• The third occipital nerve, the superficial medial branch of the C3 dorsal ramus. It crosses the outer C2-3 facet joint and supplies it.
• The C2-3 zygapophysial (facet) joint itself, a known source of headache after whiplash.

They sit close together, and they all report through the same relay. Symptoms alone cannot tell them apart. That one fact is why this problem is so often mislabeled.

What does a headache from the neck feel like?

Patients describe this pattern so often that it should be a clue, not a curiosity. The pain lights up under the skull, travels over the top of the head, and pools behind the eye on the same side, every time.

That is the shared relay doing exactly what it does. Your brain gets a signal on a pathway shared by the neck and the face. It has no reliable way to know which end the signal started at. So it blames the face and the eye. That area feels far more “headache” than “neck.”

How it moves is the second clue. The source is a joint or a nerve in the neck, so the pain answers to neck movement. Turning toward the painful side can bring it on. A blind-spot check sets it off. A night in a bad position sets it off for two days. The standard headache workup does not test for any of that.

Notice the side-locking too. Cervicogenic headache shows up as an ache locked to one side, because the structure causing it sits on one side. That is a reason to examine the upper neck. On its own, it is not a diagnosis. Symptoms alone still cannot tell these conditions apart.

What the standard headache pathway misses

None of this is any one doctor’s failure. It is a routing problem.

Headache is coded as a brain problem, so it gets sent down a brain checklist. That checklist has no step that says examine the upper neck. In a fifteen-minute headache visit, the things that go undone are predictable. Nobody presses on the C2-3 joint. Nobody checks whether turning to the painful side brings on the headache. Nobody asks about a rear-end crash or a fall from years earlier. A brain MRI gets ordered and comes back normal. Normal gets treated as an answer. It only rules out one kind of answer.

Medication has its place in headache care. What it cannot do is find which structure is causing the pain. That is a different question. It takes an exam and a procedure to answer, not a longer drug list.

What are the red flags with a headache that starts in the neck?

Before any of the above matters, disaster has to be ruled out. This part is not optional, and it is not a pain-clinic problem.

A new, abrupt, or thunderclap headache needs urgent evaluation, not an injection. So does headache with any of the following:

• neurologic deficit (such as weakness or numbness)
• fever
• jaw claudication (pain in the jaw with chewing)
• vision loss
• scalp tenderness in an older patient
• signs of spinal cord compression

Carotid or vertebral artery dissection (a tear in a neck artery), a mass or bleed in the skull, cervical myelopathy (spinal cord squeeze in the neck), and giant cell arteritis are checked urgently. They are not injected. Only when all of those are ruled out do we look at the harmless causes.

How is cervicogenic headache different from occipital neuralgia and migraine?

Occipital neuralgia is a nerve problem. The pain is stabbing and electric. It follows the path of the greater, lesser, or third occipital nerve, most often the greater. There is often a tender point where the nerve pokes through the tissue layer. Often that patch of scalp feels different, too.

Cervicogenic headache is a referral problem. The pain is made by a neck structure and felt in the head. Most often that structure is the C2-3 joint. It can also be the disc, the deep muscle, or the occipital nerve itself. It shows up as a steadier ache locked to one side. Neck position and movement bring it on, and the exam finds limited turning.

Migraine has its own signature: nausea, light sensitivity, sound sensitivity, throbbing pain, family history.

They overlap because they share that relay. History and exam narrow the field but do not close it. The test that comes closest to an answer is a numbing test, not a scan. And it only works when it is repeated under control.

How is a cervicogenic headache diagnosed?

Here is the step that gets skipped almost everywhere.

A diagnostic block puts a small amount of numbing medicine onto one named target under image guidance. Ultrasound guides the occipital nerve blocks. Fluoroscopy (live X-ray) guides the third occipital nerve and the cervical medial branch blocks. Then we measure what your headache does while that numbing medicine is known to work. It is asking a question. On its own, it is not the treatment.

And one positive block is not an answer. Barnsley and Bogduk showed in the Clinical Journal of Pain in 1993 that a single uncontrolled cervical block gives a false positive roughly twenty-seven percent of the time. That is exactly why one block is never enough. It is also why the block still has to be done. Nothing else tests the source directly.

The fix is a controlled comparative block. The block is repeated weeks later with a numbing drug that lasts a different length of time. What you want is concordant (matching) relief across two blocks, with each one lasting as long as its drug should. Not excitement after one.

The multispecialty consensus guidelines published by Hurley and colleagues in Regional Anesthesia and Pain Medicine in 2022 cover cervical facet joint pain. They favor medial branch blocks over injecting into the joint as the better predictor. (Established guideline position — but note that this guidance addresses cervical facet joint pain, not headache specifically.) How these blocks are aimed and staged is laid out on the severe head and neck pain treatment page.

One more point of honesty about the drug in that syringe. A plain numbing block lasts hours to a day or two. Its value is the information. Adding a steroid may stretch relief to weeks in some patients, but the evidence is weaker. Do not start, stop, or change any medication without consulting your physician.

What the evidence actually shows — at its true weight

This is the part that usually gets sanded down. It should not be.

The randomized data. Naja and colleagues ran a double-blind, saline-controlled randomized trial in cervicogenic headache. It was published in Pain Practice in 2006, with forty-seven patients analyzed. Occipital nerve blocks, guided by a nerve stimulator, cut pain scores roughly fifty percent from baseline and cut painkiller use significantly more than saline did. (Established finding — but from a single small randomized, saline-controlled trial: short-term and imprecise.) Three caveats come with it, and each one matters:

1. Follow-up was only two weeks. That trial tells you nothing about lasting relief.
2. The injectate was bupivacaine, lidocaine, clonidine and fentanyl.
3. Because of that mixture, this trial does not validate the plain local anesthetic block, or the anesthetic-plus-steroid block, that you would actually be offered.

It is the best randomized signal that exists here. It is not a result anyone should expect to get. Individual results vary.

The neurotomy data. If comparative blocks confirm a third occipital nerve source, radiofrequency neurotomy is worth discussing. It heats the nerve to cut off the signal. Govind, King, Bailey and Bogduk reported in the Journal of Neurology, Neurosurgery and Psychiatry in 2003 that forty-three of forty-nine patients met a hard goal. They had complete relief for at least ninety days, got back to normal daily life, and took no headache medicine at all. The median duration was two hundred ninety-seven days.

Read the design before you read the number. It is a single-center, open-label, uncontrolled series from the group that invented the technique. Patients were picked by controlled comparative blocks. There is no sham-controlled trial of this procedure. Do not inflate the figure. Looser patient selection or a different technique would likely give lower numbers. (Low-certainty evidence — uncontrolled series.)

And the relief is a window, not a cure. The nerve grows back. In that same series, fourteen patients had the neurotomy repeated when the nerve grew back; twelve regained relief, with a median of two hundred seventeen days. The honest shape of this is a window you can repeat. It is not a one-time cure, and not a single roll of the dice. Individual results vary.

What about nutrition and light therapy? Ketogenic eating, specialized pro-resolving mediators, and red and near-infrared photobiomodulation (light therapy) are still adjunctive and emerging for this condition. Their mechanisms come mostly from lab and animal work. There is no controlled human outcome data in occipital neuralgia or cervicogenic headache. Support, never the answer.

The risks, said out loud

After third occipital nerve neurotomy, some effects are expected, not rare. Unsteadiness and ataxia (loss of balance) occur in most patients. Scalp numbness occurs in about half. A small share get painful post-neurotomy neuralgia (nerve pain after the neurotomy).

Beyond that: bleeding, infection, fainting (vasovagal reaction), allergic reaction, injection into a blood vessel with numbing-drug toxicity, and no relief at all. When a steroid is used, add high blood sugar plus hair loss, skin thinning, or skin lightening at the injection site.

Relief lasts, but it is not permanent. Any description of this procedure that leaves out the regrowth is incomplete. The expected effects above should be talked through in full before you consent, not found out afterward.

An honest picture of a good outcome

What follows is a composite. It is a picture built from many patients with this condition, not one person’s chart.

Picture someone rear-ended who heals from the obvious injuries. Months later they are left with a right-sided headache running from the back of the skull to the eye. Four years of migraine treatment. Normal imaging. On exam, turning to the right is limited and brings on the headache. The C2-3 joint is tender. A third occipital nerve block, guided by fluoroscopy (live X-ray), wipes out the headache for as long as the numbing drug lasts. A comparative block weeks later, with a different drug, does the same. Only then is neurotomy offered.

The first weeks are truly unpleasant. The world tilts when they walk. A patch of scalp feels like leather. Someone else drives. The neck still has to be rebuilt: deep neck flexor endurance, shoulder-blade control, posture work. Sleep, blood sugar control, and inflammation are worth tending in anyone carrying chronic pain. But no data says they drive this particular headache, so we make no such claim here. Somewhere in the third month, the headache stops being the first thing they think about. Not gone. Not first. Individual results vary.

What this means for your evaluation

Is your headache one-sided? Does it start below the skull and move with your neck? Then make a specific request. Ask for the differential you were never given.

1. Rule out the dangerous causes first. New, sudden, or thunderclap headache, neurologic deficit, fever, jaw pain with chewing, vision loss, scalp tenderness in an older patient, or signs of cord compression need urgent evaluation, not procedures.
2. Insist the upper neck is actually examined. Pressing on the C2-3 joint, testing neck turning, and a history that includes old crashes and falls.
3. Ask whether a diagnostic block is appropriate. Understand it as a question being asked, with a measured answer over a known time.
4. Insist that any ablation be preceded by two concordant blocks, not one. The twenty-seven percent false-positive rate of a single uncontrolled block is the whole reason.
5. Rehabilitate the neck regardless. No procedure replaces deep neck flexor endurance, shoulder-blade control, and posture work.

Key takeaways

• Upper neck nerves meet the face nerve’s fibers in the trigeminocervical nucleus. That is why a sore structure under the skull can be felt behind the eye.
• Four structures can cause it: the greater, lesser, and third occipital nerves and the C2-3 facet joint. Symptoms alone cannot tell them apart.
• Dangerous causes such as artery tears, problems inside the skull, spinal cord squeeze, and giant cell arteritis are ruled out urgently before any procedure is considered.
• A single positive block is falsely positive roughly twenty-seven percent of the time. The standard is matching relief on two controlled comparative blocks.
• The evidence is honest but limited. There is one small randomized trial with two-week follow-up and an unusual drug mix. There is one uncontrolled open-label neurotomy series with no sham control.
