Occipital Neuralgia

Shooting pain from the occipital nerves at the back of the head — often mistaken for migraine.

In brief

Shooting or stabbing pain over the back and top of the scalp
Arises from the greater, lesser and third occipital nerves
Estimated incidence around 3.2 per 100,000 per year
Diagnosis is clinical; a nerve block can help confirm it
Treated with medication, nerve blocks and, in selected cases, surgery

What is Occipital Neuralgia?

Occipital neuralgia (ON) is a painful condition characterised by paroxysmal, shooting or stabbing pain arising from the occipital nerves — the nerves that supply sensation to the back and top of the scalp. The pain is felt in the distribution of one or more of three nerve pairs: the greater occipital nerve (GON), the lesser occipital nerve (LON), and the third occipital nerve (TON). ON has an estimated incidence of approximately 3.2 per 100,000 people per year.¹ It affects both sexes, with a modest female predominance. It can occur at any age, including in children and adolescents. It is frequently misdiagnosed as migraine, tension headache, or cervicogenic headache — conditions with which it shares overlapping symptoms and anatomical territory — and patients often experience diagnostic delays of months to years.

What Causes Occipital Neuralgia?

The occipital nerves arise from the upper cervical nerve roots (primarily C2 and C3) and travel upwards through muscles and connective tissue at the back of the neck before piercing through the muscles to supply the scalp. Irritation, compression, or injury at any point along this course can cause ON. In the majority of patients no specific structural cause is found — the pain is either idiopathic or attributed to irritation or entrapment of the nerves as they pass through the neck muscles. When an identifiable cause is present, it is most often one of the following:

Nerve entrapment (the most common mechanism) — the GON pierces through the semispinalis capitis muscle in approximately 90% of people and through the trapezius aponeurosis in approximately 45%, creating potential anatomical sites where the nerve may become compressed or entrapped²
Trauma — whiplash injury, direct impact to the back of the head or neck, or prior cervical surgery causing scarring around the nerve
Degenerative cervical spine disease — arthritis or disc disease of the upper cervical spine (C1–C2, C2–C3) compressing nerve roots
Less common causes — tumours or other mass lesions, inflammatory conditions such as rheumatoid arthritis of the upper cervical joints, and rarely, giant cell arteritis

What are the Symptoms?

The International Headache Society (ICHD-3) defines ON as unilateral or bilateral paroxysmal, shooting or stabbing pain in the distribution of the greater, lesser, or third occipital nerves, sometimes accompanied by reduced sensation or altered sensation (dysaesthesia) in the affected area, and commonly associated with tenderness over the involved nerve(s).³

In practice, symptoms typically include:

Sudden, sharp, shooting or electric shock-like pain starting at the base of the skull and radiating upward over the scalp toward the forehead and behind the eye
Tenderness on firm pressure over the greater occipital nerve (at the back of the skull, roughly one third of the way between the mastoid and the midline) — this is a characteristic and important examination finding
Scalp sensitivity (allodynia) — the scalp feels painful or abnormally tender to light touch, making it difficult to lie on a pillow, brush hair, or wear glasses or a hat
Pain that may radiate forward to the temple, forehead, or behind the eye on the affected side

The pain is typically unilateral, affecting one side in around 80% of people,⁴ and usually begins on one side; it is only rarely bilateral at onset, though it may extend to both sides in the remainder. It may occur in bursts or persist as a more constant ache with intermittent sharp exacerbations.

What Conditions Can be Confused with Occipital Neuralgia?

ON is one of the most commonly misdiagnosed conditions in headache medicine.³ Conditions frequently confused with ON include:

Migraine — the most common diagnostic overlap; migraine is a primary brain-generated headache, typically throbbing, often with nausea, and associated with light and sound sensitivity; it lacks the focal nerve tenderness characteristic of ON. Importantly, occipital nerve blocks can relieve both ON and migraine, making the block non-specific as a diagnostic test⁵
Cervicogenic headache — referred pain from the upper cervical joints or discs, typically provoked by neck movement, side-locked, and non-lancinating; does not have the paroxysmal electric-shock quality of ON
Tension-type headache — dull, bilateral, band-like pressure, without the nerve-distribution pattern or focal tenderness of ON
Cluster headache — severe periorbital and temporal pain occurring in cyclical patterns, associated with autonomic features (tearing, nasal congestion, drooping eyelid)
C2 radiculopathy — pain from C2 nerve root compression in the cervical spine; distinguished by cervical imaging and examination findings
Greater occipital neuritis from giant cell arteritis — inflammation of the scalp arteries in older patients; distinguished by elevated inflammatory markers (ESR, CRP), jaw claudication, and scalp artery tenderness
Post-herpetic neuralgia — persistent burning pain following shingles (herpes zoster) in the occipital distribution; distinguished by history of shingles rash

How is Occipital Neuralgia Diagnosed?

There is no single diagnostic test for ON. The diagnosis is made clinically — based on the characteristic pattern of pain, its distribution, and the presence of focal nerve tenderness — and is confirmed by a diagnostic nerve block.⁵

Clinical history and examination

The distribution, character, and triggers of the pain are carefully documented. A thorough neurological and musculoskeletal examination is performed, with particular attention to tenderness over the occipital nerves at the back of the skull and any signs of upper cervical pathology. Laboratory tests (blood count, inflammatory markers including ESR and CRP) are performed to exclude giant cell arteritis and inflammatory conditions.

Diagnostic nerve block

Temporary, complete or near-complete relief of pain following local anaesthetic injection around the greater or lesser occipital nerve strongly supports the diagnosis of ON and confirms the nerve as the pain source. The ICHD-3 diagnostic criteria for ON include transient pain relief from this block as a required criterion.3 It is important to note that occipital nerve blocks can also relieve migraine and cervicogenic headache, and therefore a positive response confirms nerve involvement but does not exclude coexisting headache disorders.⁵

Magnetic Resonance Imaging (MRI)

MRI of the brain and upper cervical spine may be performed to exclude secondary causes of ON — including tumours, arteriovenous malformations, cervical disc disease, or inflammatory conditions. It is not diagnostic of ON itself but can be valuable for excluding serious underlying pathology.

SPECT of the cervical spine

A SPECT scan (a type of nuclear medicine scan) of the cervical spine may be helpful in selected cases. It can detect active inflammation in the upper cervical joints — a recognised source of occipital or cervical headache — and may therefore be of diagnostic value.

How is Occipital Neuralgia Treated?

Treatment of ON is stepwise, progressing from conservative measures to more invasive options if simpler treatments fail. The majority of patients can achieve adequate pain control without surgery. Occipital neuralgia is usually managed by a neurologist or pain physician; a neurosurgeon typically becomes involved only when conservative and less invasive measures have failed and the patient is referred for consideration of surgical treatment.

Conservative Measures

Simple measures that are often helpful as initial management include:

Local heat application to the back of the neck
Gentle massage and stretching of the suboccipital muscles
Rest and activity modification to avoid neck postures that aggravate pain
Non-steroidal anti-inflammatory drugs (NSAIDs) and muscle relaxants may provide modest short-term relief, though they are generally insufficient as sole long-term treatment

Medical Management

Medications used for ON are the same as those used for other neuropathic pain conditions, with carbamazepine being the traditional first-line agent. It is important to note that no large randomised controlled trials have been performed specifically in ON, and medical treatment recommendations are largely extrapolated from evidence in other neuralgias and neuropathic pain conditions.⁶

Carbamazepine (Tegretol) is the most established first-line oral medication, widely used for neuralgias. It stabilises abnormally excitable nerve membranes. It is started at a low dose — typically 100–200 mg/day, with the lower dose used in smaller or elderly patients — and increased gradually. Common side effects include drowsiness and dizziness; blood monitoring for sodium levels and blood count is required.⁵

Pregabalin (Lyrica) and Gabapentin (Neurontin) are anticonvulsant medications with established evidence in neuropathic pain. Gabapentin 300–600 mg at bedtime is a commonly used alternative.⁵

Amitriptyline (a tricyclic antidepressant) is a useful second-line agent, particularly when sleep disruption accompanies pain.⁵

Oxcarbazepine (Trileptal) is a carbamazepine analogue that is often better tolerated, with fewer drug interactions.

Other agents that may be helpful include baclofen, lamotrigine, nortriptyline 30–50 mg at bedtime, and topical agents.⁵

Standard over-the-counter pain relievers such as paracetamol and ibuprofen are generally insufficient as primary treatment for ON.

Occipital Nerve Blocks — The Cornerstone of Management

Occipital nerve blocks — injection of local anaesthetic with or without corticosteroid around the greater and/or lesser occipital nerves — are both the primary diagnostic tool and one of the most effective treatments for ON. They provide rapid and often prolonged relief in the majority of patients and are the most widely recommended first-line interventional treatment.⁵ Multiple reviews confirm that occipital nerve blocks are effective across a range of ON presentations including post-traumatic, post-surgical, and idiopathic cases. Relief typically lasts weeks to months; the procedure can be repeated as needed. It is well tolerated and can be performed in an outpatient setting. The use of ultrasound guidance to precisely target the GON at its emergence from the suboccipital region improves needle-placement accuracy and safety and has become the preferred technique at most specialist centres. Botulinum toxin injections — injection of botulinum toxin around the occipital nerves has been used for refractory occipital neuralgia; small studies suggest benefit for some patients, though the evidence remains limited.⁶

Minimally Invasive Procedures

For patients whose pain returns between nerve blocks or who require frequent repeat injections, several more durable minimally invasive options are available:

Pulsed radiofrequency (PRF) treatment — delivers pulsed electrical energy around the occipital nerve or C2 dorsal root ganglion (DRG), reducing pain signalling without destroying the nerve. A clinical study of 10 patients found PRF to provide significant pain relief with a good safety profile.⁷

Radiofrequency ablation (RFA) — delivers controlled heat to the C2 dorsal root ganglion or third occipital nerve, producing a longer-lasting reduction in pain transmission. In a study of 40 patients with cervicogenic headache or occipital neuralgia, RFA of the C2 dorsal root ganglion and/or third occipital nerve produced at least 80% pain relief in around 70% of appropriately selected patients.⁸

Occipital Nerve Stimulation (ONS)

For patients with medically refractory ON who do not achieve adequate or sustained relief from nerve blocks and minimally invasive procedures, occipital nerve stimulation (ONS) is a well-established neuromodulation option. A small electrode is placed subcutaneously overlying the occipital nerves, connected to an implanted pulse generator, delivering low-level electrical stimulation that modulates pain signalling. The Congress of Neurological Surgeons (CNS) has published evidence-based guidelines on ONS for refractory ON, most recently updated in 2023, confirming ONS as an evidence-supported option for this indication, although the supporting studies remain lower-certainty (Class III) evidence.⁹ Studies consistently demonstrate significant reductions in pain scores, analgesic requirements, and headache frequency in appropriately selected patients, with a favourable safety profile. Hardware-related complications (lead migration, infection) are the most common issues and should be discussed with patients prior to implantation.

Surgical Treatment

Surgery is reserved for patients whose pain has not responded to conservative, pharmacological, and simpler interventional approaches. It is, however, a good alternative to neuromodulation, or an option where a specific surgically correctable cause has been identified on imaging.⁶ Being more invasive than the procedures described above, it carries greater risks, and the choice between surgery and neuromodulation is made on an individual basis.

Occipital nerve decompression (neurolysis)

Decompression — also called neurolysis — releases the greater occipital nerve from the surrounding muscle and connective tissue where it becomes entrapped, typically at the semispinalis capitis and/or the trapezius aponeurosis. Because the nerve is freed rather than divided, sensation is preserved; some temporary numbness or tingling in the area can occur but usually settles within a few months. It is the preferred, nerve-sparing surgical option and, in carefully selected patients, provides good relief — in a series of 76 patients, symptoms resolved completely in around 90%, with recurrence in under 5%.¹⁰

Occipital nerve removal (neurectomy)

Neurectomy involves dividing or removing a segment of the greater occipital nerve. It is more definitive but sacrifices the nerve, and therefore leaves permanent numbness in the area of scalp it supplies. It is generally reserved for patients whose pain persists or returns after decompression, or in whom the nerve is scarred. Good relief is achieved in around 70% of such patients, but recognised drawbacks include the expected numbness, the risk of a tender nerve-end swelling (neuroma) or persistent deafferentation pain, and the possibility of pain recurring as the nerve regrows.¹¹ Because neurectomy is irreversible and leaves lasting numbness, it is undertaken only after careful discussion of these trade-offs and is best performed by a surgeon experienced in occipital nerve surgery.

What Happens if Occipital Neuralgia is Left Untreated?

ON is not life-threatening and does not damage the brain or spinal cord. For patients whose pain is well controlled with nerve blocks or medications, conservative management is entirely appropriate. Without treatment, the pain typically persists and can significantly impair quality of life — affecting sleep, concentration, work, and daily activities. Spontaneous remission can occur but is unpredictable. ON does not shorten life expectancy.
