What Is the Occipital Muscle and Why Does It Hurt?

The occipitalis is a thin, flat muscle at the back of your skull, and pain in that area usually has less to do with the muscle itself than with the nerves threaded through and around it. The occipitalis sits over the back of the head and connects to the same broad sheet of tissue as the frontalis muscle above your eyebrows, forming a unit sometimes called the occipitofrontalis. When people complain of occipital pain, though, the culprit is typically nerve compression, trigger points in deeper neck muscles, or tension headache patterns that radiate into the back of the skull. Understanding which structures actually live in that region explains why “the back of my head hurts” can mean so many different things.

Where the Occipitalis Sits and What It Does

The occipitalis muscle is remarkably thin. An anatomical study measuring it on cadaveric specimens found its average thickness was only about 0.27 mm, with a width of roughly 45 cm across both sides and a vertical length of about 59 cm. Its lower edge attaches near the superior nuchal line, a bony ridge you can feel running across the lower back of your skull, and its upper fibers merge into a tough sheet of connective tissue called the galea aponeurotica that covers the top of the head like a cap. The muscle itself crosses the lambdoid suture, the seam between your skull’s parietal and occipital bones.¹

Functionally, the occipitalis does not do very much on its own. Its main job is pulling the scalp backward, which works in tandem with the frontalis pulling it forward to raise your eyebrows or wrinkle your forehead. You have relatively little voluntary control over the occipitalis compared to the muscles in your face. Because it is so thin and does so little heavy lifting, the muscle itself is rarely the direct source of pain. The real action happens in the deeper structures beneath and around it.

The Greater Occipital Nerve and Its Compression Points

The greater occipital nerve is the main sensory nerve serving the back of your head, and it has to travel through a gauntlet of muscles to get there. A dissection study mapped six distinct points where the nerve can be compressed along its course. Starting deep in the neck, it first gets squeezed between the semispinalis muscle and the obliquus capitis inferior near the spine. Then it passes into and back out of the semispinalis, creating two more potential pinch points. Higher up, it enters the trapezius muscle, exits through the trapezius’s thick fascia where it attaches to the nuchal line, and finally may be crossed by the occipital artery, which can press on it from outside.²

The nerve’s path through the trapezius is not even consistent from person to person. In a study of cadaveric specimens, the nerve simply passed along the lateral border of the trapezius and pierced only the fascia connecting the trapezius to the sternocleidomastoid in about 63% of cases, while in the remaining 37% it actually pierced through the trapezius muscle itself.³ That anatomical variation helps explain why some people are more prone to nerve irritation in that area than others. When any of these muscles tighten, swell, or develop adhesions, they can clamp down on the nerve and produce shooting, burning, or throbbing pain across the back of the head.

Occipital Neuralgia Versus Cervicogenic Headache

Two conditions frequently cause pain at the back of the skull, and they are often confused with each other. Occipital neuralgia is a nerve problem: the greater or lesser occipital nerve is irritated or damaged, producing sharp, electric-shock-like pain that follows the nerve’s path from the upper neck across the back of the scalp. Cervicogenic headache, by contrast, is a referred-pain condition where problems in the cervical spine or its muscles send pain signals up into the head, producing a duller ache that often spreads to the forehead or behind the eyes.

One review noted that the prevalence of cervicogenic headache ranges from about 4% to 20% depending on whether the study looked at the general population or hospital patients, while the incidence of occipital neuralgia is reported at about 3.2%, peaking between ages 60 and 69 and slightly more common in women.⁴ Although the two overlap in symptoms, the distinction matters because treatments differ. Occipital neuralgia often responds to nerve blocks or ablation, while cervicogenic headache may require addressing the underlying spinal or muscular dysfunction. The reality for many patients is that both processes can be active at the same time, muddying the diagnosis.

Forward Head Posture and the Suboccipital Muscles

Beneath the occipitalis and the superficial neck muscles sits a group of four small, deep muscles collectively called the suboccipital muscles. These muscles connect the top two vertebrae (the atlas and axis) to the base of the skull and serve as fine-tuned stabilizers of head position. They contain an unusually high density of muscle spindles, the tiny sensory organs that tell your brain where your head is in space, making them more like precision sensors than power generators.

When you spend hours with your chin jutting forward, as most desk workers do, these muscles are held in a shortened, contracted state. A review of the relationship between suboccipital muscles and posture found that structural and functional changes in these muscles can induce dizziness, partly through connections called myodural bridges that link the muscles to the membrane covering the spinal cord. Trigger points in the suboccipital muscles, stimulated by abnormal head posture, may contribute to cervicogenic dizziness.⁵ So if the back of your head hurts and you also feel lightheaded or off-balance, the suboccipital muscles are a plausible link.

These muscles also show anatomical variation. A cadaveric study found bilateral variations in the rectus capitis posterior minor muscle in about 11% of specimens, and an extra muscle called the atlantomastoid was present in about 11% of cases as well.⁶ These variants may change how forces are distributed across the upper neck and base of the skull, potentially making some people more vulnerable to pain in the occipital region.

Trigger Points and Referred Pain That Travels

Trigger points are hyperirritable spots within taut bands of muscle that can produce pain far from where they are located. The occipital region is a hotspot for them, and the referred pain patterns can be surprising. A study examining patients with a specific type of eye pain found that trigger points in the occipital region and trapezius were strongly correlated with deep, persistent pain behind the eye socket on the same side. All 81 patients with this pattern of referred pain had occipital trigger points, and multivariate analysis confirmed the correlation was highly significant.⁷

This means that pain you feel behind your eye, along your temples, or at the top of your head may actually originate from a knotted muscle at the base of your skull. The mechanism involves convergence of nerve signals: sensory fibers from the upper neck share relay stations in the brainstem with fibers from the face and head, so the brain can misinterpret where the pain is coming from. If you have been chasing the cause of stubborn eye pain or temple headaches with eye exams and sinus treatments, the source may be sitting at the back of your neck.

How Tension Headache Becomes Chronic

The most common form of occipital-area pain is plain tension-type headache, which affects roughly half of adults at some point. Increased tenderness to palpation of the muscles around the skull is the most apparent abnormality in these patients. Research has shown that prolonged nociceptive input from these pericranial muscles can sensitize the neurons in the brainstem’s trigeminal nucleus, amplifying pain signals beyond what the actual tissue damage warrants.⁸ Once that sensitization sets in, the pain system essentially turns up its own volume, and even light pressure on the back of the head can feel disproportionately painful.

This process appears to be what converts occasional tension headaches into chronic ones. A model proposed by headache researchers distinguishes between episodic and chronic tension-type headache: peripheral muscle mechanisms dominate in the episodic form, while central sensitization drives the chronic form.⁹ The practical takeaway is that if your occipital headaches have been gradually getting worse and more frequent over months, intervening earlier is better than waiting. Once the brainstem has been rewired to amplify pain signals, treatment becomes harder. Addressing the muscle tension that feeds those signals can help prevent the shift from occasional to constant.

Jaw Clenching and Its Surprising Connection

Most people would not connect jaw tension with pain at the back of the skull, but the two are linked through involuntary co-contraction. When you clench your jaw, your neck muscles activate too, even though you are not consciously tightening them. Research using electromyography found that jaw clenching tasks triggered co-contractions in neck muscles at levels between 3% and 10% of their maximum voluntary force, with the magnitude and pattern varying depending on the direction and strength of the jaw contraction.¹⁰

That may sound small, but consider someone who grinds their teeth at night for eight hours, or unconsciously clenches their jaw during a stressful workday. The neck muscles, including those attached around the occipital bone, are contracting at a low level the entire time. Over days and weeks, that steady background tension can produce the same trigger points and muscle fatigue that more obvious overuse would cause. If you wake up with pain at the base of your skull and have been told you grind your teeth, the two are probably related.

Whiplash and Lingering Occipital Pain

Cervicogenic headache with pain radiating from the neck to the forehead is a common finding after whiplash injury. Post-whiplash cervicogenic headache typically produces moderate pain, but the course is often prolonged and comes with substantial disability and high use of medication.¹¹ The mechanism involves damage to the upper cervical joints and the muscles and ligaments that stabilize them. After the acute injury heals, the altered mechanics can keep irritating the nerves and muscles that refer pain to the back of the head. This is one reason whiplash patients who were told “everything looks fine on imaging” may still have persistent occipital pain months or years later: the problem is functional, not structural, and standard imaging often does not capture it.

Diagnosing the Source With Ultrasound

Figuring out exactly why the back of your head hurts used to be mostly a clinical guessing game based on where it hurt when pressed. Ultrasound is changing that picture. It can image the occipital nerves in real time, distinguish normal from abnormally entrapped nerves, and identify both the level and cause of entrapment.¹² This is a significant step up from injecting an anesthetic into the general area and seeing whether the pain goes away, which has been the standard diagnostic approach for decades.

That said, ultrasound of the occipital nerves is technically challenging. The nerves are small, and the muscles of the posterolateral neck that serve as landmarks for locating them can be difficult to distinguish from one another on imaging.¹³ Not every clinic or provider has the skill set to do this well, so the practical availability of ultrasound-guided diagnosis varies widely.

Treatment Options, From Conservative to Procedural

For most people with occipital-area pain, the starting point is conservative: addressing posture, managing stress, reducing screen time, and over-the-counter pain relief. But when the pain becomes frequent or severe, several targeted treatments exist.

Dry needling of the trapezius and suboccipital muscles has shown promise. A case report documented a patient with occipital neuralgia who underwent four dry needling sessions over two weeks and experienced meaningful improvements in both neck disability and headache disability scores.¹⁴ Trigger point injections work on a similar principle but deliver a small amount of local anesthetic or saline into the knotted muscle. The mechanisms behind why trigger point injections work are still not fully understood, and their efficacy is variable, but the increasing use of ultrasound to guide needle placement into the exact site of entrapment rather than an assumed location is improving results.¹⁵

Greater occipital nerve blocks, where an anesthetic is injected around the nerve, serve both as a diagnostic test and a treatment. If a nerve block abolishes the pain temporarily, it confirms the nerve is involved and opens the door to longer-lasting interventions. A study on migraine patients found that combining trigger point injections with occipital nerve blocks was more effective than nerve blocks alone, particularly in patients with prolonged headache episodes.¹⁶ In a separate study, greater occipital nerve block, with or without trigger point injection, reduced both head pain and a type of skin sensitivity called brush allodynia in migraine patients.¹⁷

When Pain Persists: Ablation, Botox, and Nerve Stimulation

For patients who get temporary relief from nerve blocks but whose pain keeps returning, more durable options exist. Thermal radiofrequency ablation uses heat to disrupt the nerve’s ability to transmit pain signals. A study of this technique for occipital neuralgia found a significant drop in pain scores, from an average of 6.7 out of 10 before the procedure to 2.7 afterward, with patients reporting a mean of about 76% pain relief lasting an average of roughly six and a half months.¹⁸ Pulsed radiofrequency, a gentler variant, has also been used with ultrasound guidance to treat occipital neuralgia, with patients reporting immediate pain relief that lasted several months.¹⁹

Botulinum toxin, commonly known as Botox, is another option that works by paralyzing the muscles compressing the nerve and blocking the release of pain-signaling chemicals. A randomized controlled trial comparing botulinum toxin to bupivacaine for greater occipital nerve block in chronic headache patients found that the botulinum toxin group had significantly lower pain scores at 4, 8, and 24 weeks after treatment.²⁰ The advantage over a standard nerve block is duration: a single botulinum toxin injection can suppress pain for several months.

For the most refractory cases, where everything else has been tried and failed, occipital nerve stimulation is a surgical option. A small device is implanted under the skin at the back of the head, delivering mild electrical pulses to the occipital nerves to override pain signals. This approach has been used for chronic refractory migraine and has been shown to provide satisfactory pain relief and improved quality of life in patients who had exhausted other treatments.²¹ It is a last-resort intervention, but its existence reflects how seriously the medical community takes occipital pain that will not respond to less invasive approaches.

Why “Occipital Pain” Is So Often Misattributed

A recurring problem with pain at the back of the head is that people, and sometimes their doctors, fixate on the wrong structure. Someone with occipital neuralgia may be treated for tension headaches for years. Someone with suboccipital trigger points referring pain behind the eye may undergo repeated ophthalmological workups that come back normal. Someone with cervicogenic headache from a whiplash injury years ago may be told it is stress or migraines.

The anatomy explains why the confusion is so common. At the back of the skull, you have the thin occipitalis muscle on top, the thick trapezius and sternocleidomastoid muscles on the sides, the tiny suboccipital muscles deep underneath, and several nerves threading through all of them. Compression at any point along those nerve paths, or trigger points in any of those muscles, can produce pain in the same general region. The quality of the pain, whether it is sharp and electric versus dull and pressing, and whether it changes with specific head positions, helps narrow down the source. Ultrasound-guided assessment can further pinpoint entrapment. But the bottom line is that “occipital pain” is a location, not a diagnosis, and the most common mistake is treating it as one.
