How is occipital neuralgia diagnosed?

Two nerves leave the spine at the second neck vertebra. They thread through the thick muscles at the base of the skull and fan out over the back of the scalp. Press the point where the greater occipital nerve comes to the surface: a thumb-width off the midline, just below the skull. In occipital neuralgia, the headache lights up or a shock runs forward over the head. Three things make the diagnosis under the International Classification of Headache Disorders. That tenderness. The shooting quality of the pain. And the pain going away after the nerve is numbed. No scan makes this diagnosis. A fingertip and a diagnostic block do.

Between the shocks there is usually a duller ache in the same area. The scalp can get so sensitive that brushing your hair or resting your head on a pillow hurts. The pain often ends behind the eye on the same side. That is the part that sends people down the migraine road for years.

What causes occipital neuralgia, and why does it hurt behind the eye?

The nerve fibers from the top of the neck and the fibers from the face and the lining of the brain arrive at the same relay in the brainstem. This shared junction is called the trigeminocervical complex. Stimulate the occipital nerve in the lab and the neurons that handle input from the dura (the brain’s outer lining) become more excitable. The reverse is also true. The brain cannot tell which door the signal came through. So an irritated neck nerve is felt as a headache behind the eye. And a long-running occipital neuralgia can wind up the same central machinery that migraine uses. That is the first biological driver: convergence, then sensitization.

The second is the terrain the nerve runs through. Chronically high insulin and inflammatory signals from fat tissue lower the point at which nerves fire, and they slow nerve repair. In a population study of more than 30,000 adults, obesity raised the odds of chronic daily headache, and of transformed migraine in particular. Short sleep does the same thing to the same circuits within days. In a metabolically healthy person, a neuralgia is a local irritation. In a metabolically inflamed one, it is a local irritation feeding an already sensitized system. That is why the plan here treats both.

The third driver is what the neck is doing all day. The nerve passes through the semispinalis and trapezius. These muscles clench under a windshield, a screen or a rear-end collision. A muscle held tight for eight hours squeezes the nerve at the point it pierces. A crash on I-64 that left the neck stiff for months. A dispatch desk, a delivery route, a night shift with the head forward. Each one is a compression the nerve was not built to tolerate. Where a crash started it, this page covers what Illinois expects of the record.

How is occipital neuralgia treated?

What keeps occipital neuralgia from coming back?

The block buys the window. What fills it is the part that keeps the nerve from being squeezed again. The deep neck muscles are retrained to hold the head without the upper trapezius clenching. The screen is raised and the seat adjusted. The pillow is changed so the head stops falling forward for seven hours. Sleep is protected because the relay in the brainstem resets its threshold overnight, and it does not when the night is short. Bloodwork is drawn because a chronic headache in someone with a high fasting insulin has a second driver. The food plan that removes acellular carbohydrates and industrial seed oils addresses it. Acceptance and Commitment Therapy is delivered in-house by a licensed, pain-trained behavioral clinician, because a scalp that hurts to touch teaches a person to stop moving the neck, and a neck that stops moving squeezes the nerve harder. That work is 40 to 50 percent of the plan.

Sometimes the exam points to the joint between the second and third neck vertebrae, not the nerve. Then the plan moves to that page. The two share an area, and a diagnostic block tells them apart. From Fairview Heights the clinic is about 35 minutes without traffic on I-64 to I-170 north; from Wood River, about 30 by I-255 and I-270. The consultation and the diagnostic block are done on the same visit when the exam supports it.

Frequently asked questions

Do I need a referral for occipital neuralgia?

No. You can book a visit for headaches at the base of the skull yourself. Some insurance plans, mostly HMOs, ask for a referral on file before they pay, so check your card. The nerve block that confirms it is a test as much as a treatment; what a diagnostic block tells you explains why.

How is occipital neuralgia different from migraine?

Migraine is a brain event with nausea, light sensitivity and a build over hours. Occipital neuralgia is a nerve event: shooting pain from a tender point at the back of the skull that a local anesthetic switches off. The two can coexist. The block is what tells you how much of the headache belongs to the nerve.

Could it be the joints in my neck instead of the nerve?

The joint between the second and third vertebrae sends pain into the same area. The exam and a targeted block separate them; the medial branch block is the test for the joint.

It started after a rear-end crash on I-64. Is that typical?

Whiplash strains the muscles the nerve passes through and can irritate the nerve directly. Occipital pain months after a crash is a known pattern. The record matters in Illinois, and this page explains what we document and why.

Why does a pain clinic ask about my sleep and my blood sugar for a headache?

Because the relay that turns a neck-nerve signal into a headache is more excitable after short sleep and in a body with high insulin, so both change how often the headache fires. This page covers what is prescribed and the body science behind it.

What worsens occipital neuralgia?

Anything that keeps the neck muscles clenched around the nerve. Think of hours with the head pushed forward toward a windshield or a screen, a night shift, a delivery route, or the stiffness left by a rear-end crash. Short sleep makes the brainstem relay more excitable within days. High insulin lowers the point at which the nerve fires. Once the scalp is sensitized, even brushing your hair or resting on a pillow can set it off.

What should you not do with occipital neuralgia?

Do not keep treating it as migraine with one more drug when a fingertip on the back of the skull brings on the headache. It is treated at the nerve. Do not stop moving your neck because the scalp hurts, since a neck that stops moving squeezes the nerve harder. And do not agree to have the nerve cut: a cut sensory nerve regrows, and the result is often worse than the original.

Will occipital neuralgia ever go away?

The plan is built to make it go quiet and stay quiet. A block often gives relief that outlasts the anesthetic by weeks, because quieting the nerve lets the sensitized relay in the brainstem settle. What keeps it from coming back is the work that follows: retraining the neck muscles, protecting sleep and lowering insulin. When relief does not last, pulsed radiofrequency and then a trial of a nerve stimulator are the next steps.

Can the wrong pillow cause occipital neuralgia?

A pillow that lets your head fall forward for seven hours adds one more long stretch with the nerve squeezed where it passes through the neck muscles. That is why the pillow is part of the plan here. So are a raised screen, an adjusted seat, and deep neck muscles retrained to hold the head without the upper trapezius clenching. A sensitized scalp can also make simply resting on a pillow hurt.
