Introduction

Occipital neuralgia (ON) is a painful cranial neuropathy classified under section 13.4 of the International Classification of Headache Disorders, Third Edition (ICHD-3). It is characterised by paroxysmal, unilateral or bilateral shooting or stabbing pain arising in the distribution of the greater occipital nerve (GON), lesser occipital nerve (LON), and/or third occipital nerve (TON). Pain typically originates at the posterior cranial base and may radiate anteriorly to the fronto-orbital region via trigeminocervical interneuronal connections within the trigeminal spinal nuclei.

ON is considered a rare condition. Epidemiological data remain limited, as no population-based studies have been identified in the literature. A 2025 systematic review and meta-analysis identified 15 clinic-based studies comprising 579 persons with ON, but was unable to derive a reliable general population incidence estimate from the available evidence. The condition accounts for 0.6–24.4% of presentations to specialist headache or facial pain clinics, with wide variation reflecting the absence of a standardised gold-standard diagnostic test and ongoing ambiguity in current classification criteria.

Clinically Relevant Anatomy

The occipital nerves are sensory branches supplying the posterior scalp and upper cervical region. Understanding their anatomy is essential for accurate clinical assessment and procedural interventions.

The GON is the primary nerve implicated in ON. It arises from the medial branch of the dorsal ramus of the second cervical spinal nerve (C2) and courses superiorly through the semispinalis capitis and trapezius muscles before piercing the deep cervical fascia near the superior nuchal line. Sites of potential entrapment include the semispinalis capitis, the trapezius aponeurosis, and the greater occipital notch.

The LON arises from the ventral rami of C2 and C3 and ascends along the posterior border of the sternocleidomastoid muscle to supply the posterior auricle and lateral scalp.

The TON is the medial branch of the dorsal ramus of C3, supplying the upper posterior cervical region. It is the least frequently implicated nerve in ON.

Aetiology

ON is broadly classified as either primary (idiopathic) or secondary (attributable to an identifiable underlying cause). The most widely accepted pathophysiological mechanism is chronic entrapment or compression of the occipital nerves, most commonly by the posterior cervical musculature.

Primary Occipital Neuralgia

Primary ON arises without an identifiable systemic or structural cause. Contributing factors include compression of the GON, LON, or TON by hypertrophic or chronically contracted posterior cervical musculature, postural dysfunction resulting in sustained mechanical load on the upper cervical structures, and direct trauma to the occipital region including [Whiplash Associated Disorders|whiplash-associated disorders]].

Secondary Occipital Neuralgia

Secondary ON arises as a consequence of an underlying pathological process. Recognised aetiologies include osteoarthritis of the upper cervical zygapophyseal joints (C1–C2, C2–C3), degenerative disc pathology causing nerve root compression, systemic inflammatory or metabolic conditions including gout, diabetes mellitus and vasculitis, infectious or post-infectious neuritis, neoplastic processes involving the cervical spine or posterior fossa, and vascular malformations or arteriovenous abnormalities in proximity to the occipital nerves.

Clinical Presentation

Persons with ON typically report episodic, severe paroxysmal pain lasting seconds to minutes, described as shooting, stabbing, or electric shock-like in quality. Pain onset is typically at the posterior cranial base and may radiate along the ipsilateral scalp to the retro-orbital region. Characteristic clinical features include:

• Paroxysmal, unilateral or bilateral posterior cranial pain in the distribution of the GON, LON, and/or TON
• Cutaneous allodynia (heightened pain sensitivity to normally non-painful stimuli), dysaesthesia (unpleasant abnormal sensation), or hypoaesthesia in the affected dermatomal distribution
• Tenderness on palpation over the course of the affected nerve(s)
• A positive Tinel sign (reproduction of neuritic pain by percussion) at the greater occipital notch
• Pain aggravated by light touch, combing, or brushing of the posterior scalp
• Anterior radiation to the fronto-orbital region on the ipsilateral side
• Temporary pain relief following local anaesthetic nerve block (required for ICHD-3 diagnosis)

Unlike migraine, ON is not typically associated with nausea, photophobia, or phonophobia, although comorbid migraine occurs in a proportion of persons. A 2025 systematic review and meta-analysis reported that ON presents most commonly in the fifth decade of life, with a predominance among females (73%).

Differential Diagnosis

Accurate differential diagnosis is essential, as the pain distribution of ON overlaps with several other headache and cervicogenic pain disorders. The following conditions must be considered and excluded before confirming a diagnosis of ON:

• Cervicogenic Headache – Cervical provocation reproduces the headache; restricted cervical range of motion; pain not confined to occipital nerve dermatomal distribution
• Migraine – Moderate to severe pulsating pain lasting 4–72 hours; associated nausea, photophobia, or phonophobia; aggravated by routine physical activity
• Tension-Type Headache – Bilateral pressing or tightening quality; mild to moderate intensity; pericranial tenderness without neurological signs
• Cluster Headache – Strictly unilateral orbital or temporal pain; ipsilateral autonomic features (lacrimation, rhinorrhoea); episodic clustering pattern
• Atlanto-axial or upper zygapophyseal joint pain – Pain arising from joint referral confirmed by diagnostic joint block rather than nerve distribution
• Myofascial trigger point referral – Reproduction of pain by pressure over trigger points in the suboccipital, sternocleidomastoid, or trapezius muscles; absent neurological signs

Accurate differentiation between ON and occipital migraines is of particular clinical importance, as treatment pathways differ substantially.

Diagnosis

Diagnosis is primarily clinical, integrating a thorough history, physical examination, and neurological assessment with the ICHD-3 diagnostic criteria. There is no single gold-standard diagnostic test for ON.

ICHD-3 Diagnostic Criteria

The ICHD-3 requires all of the following criteria to be fulfilled for a diagnosis of ON (Section 13.4):

1. Pain in the distribution of the GON, LON, and/or TON
2. Pain has at least two of the following characteristics: (a) recurring in paroxysmal attacks lasting seconds to minutes; (b) severe intensity; (c) shooting, stabbing, or sharp quality
3. Pain is associated with both of the following: (a) dysaesthesia and/or allodynia during innocuous stimulation of the scalp and/or hair; (b) either or both of tenderness over the affected nerve branches or a Tinel sign over the GON
4. Pain is eased temporarily by local anaesthetic block of the affected nerve(s)

A single diagnostic nerve block carries a false-positive rate of up to 40%; a second confirmatory block is therefore recommended where the first block is positive.

Physical and Neurological Examination

Clinical assessment should include:

• Palpation along the course of the GON, LON, and TON
• Assessment of the Tinel sign at the greater occipital notch
• Evaluation of upper cervical active and passive range of motion
• Neurological screening of the upper extremities to exclude cervical radiculopathy
• Systematic assessment of allodynia and dysaesthesia in the occipital dermatomes using light touch, pinprick, and cold detection testing

Imaging

Advanced imaging (MRI or CT of the cervical spine and posterior fossa) is not required for routine ON diagnosis but should be considered where secondary ON is suspected, where the clinical presentation is atypical, or where initial conservative management has not produced a clinical response.

Ultrasound-Guided Assessment

High-resolution ultrasound has an emerging role in ON management. It enables direct visualisation of the GON and guides precise nerve block administration, reducing the false-positive rate associated with landmark-based injection and improving diagnostic specificity.

Management

Management of ON is guided by symptom severity, response to initial conservative measures, and whether the neuralgia is primary or secondary in nature. A stepwise, multimodal approach is recommended, progressing from conservative to interventional strategies as clinically indicated.

Conservative Management

Physiotherapy and Physical Rehabilitation

Conservative management, including physiotherapy, is consistently recommended as the first-line intervention for ON; however, the published evidence base specific to physiotherapy interventions remains limited. A 2024 systematic review identified very low-quality evidence supporting transcutaneous electrical nerve stimulation (TENS) as a conservative intervention for ON, and proposed a mechanism-based framework for management informed by the person's clinical phenotype rather than diagnosis alone.

Based on available mechanistic rationale and evidence from adjacent headache and cervicogenic pain literature, the following physiotherapy interventions are commonly employed:

• Manual therapy – Cervical joint mobilisation and manipulation targeting C1–C3 zygapophyseal joints to address contributing articular dysfunction
• Suboccipital soft tissue and myofascial release – Targeting the semispinalis capitis, sternocleidomastoid, and upper trapezius to reduce compression at known nerve entrapment sites
• Therapeutic exercise – Progressive cervical stabilisation, deep neck flexor strengthening, and postural correction to reduce chronic mechanical load on upper cervical structures
• TENS – Applied to the occipital region; currently supported by the highest-quality conservative intervention evidence available for ON
• Dry needling and acupuncture – A 2020 systematic review and meta-analysis reported improvements in pain outcomes compared with medication alone; study heterogeneity and small sample sizes limit the strength of these conclusions
• Education and self-management – Ergonomic advice, activity pacing, sleep positioning, and avoidance of allodynic triggers (e.g., tight headwear, vigorous hair brushing)

The following practice points reflect current evidence and clinical reasoning principles for physiotherapy management of ON:

• Conduct a systematic upper cervical musculoskeletal and neurological assessment to characterise the clinical presentation and exclude cervicogenic or other diagnoses prior to treatment
• Adopt a mechanism-based treatment framework, targeting identifiable contributors such as suboccipital muscular hypertension, upper cervical joint dysfunction, and postural loading patterns
• Coordinate with the broader clinical team — including pain medicine, neurology, and interventional specialists — as multimodal care optimises outcomes
• Educate persons regarding the chronic-relapsing nature of ON, the rationale for physical treatment, and strategies to manage allodynic triggers
• Assess psychological comorbidities (anxiety, depression, sleep disturbance) that are common in chronic pain presentations and may require concurrent management
• Document response to treatment using validated outcome measures, including the Numeric Pain Rating Scale (NPRS), Headache Impact Test (HIT-6), and Patient-Specific Functional Scale (PSFS)
• Reassess and escalate to interventional management where conservative physiotherapy over 6–8 weeks does not produce clinically meaningful improvement

Thermotherapy

Application of heat to the posterior cervical region may reduce muscular tension and provide symptomatic relief. A barrier (e.g., a towel) should be placed between the heat source and the skin to prevent thermal injury and excessive stimulation of occipital cutaneous nerve endings.

Pharmacological Management

Pharmacological therapy serves as an adjunct to physical management and includes:

• Non-steroidal anti-inflammatory drugs (NSAIDs) for short-term analgesia
• Tricyclic antidepressants (e.g., amitriptyline) or serotonin-norepinephrine reuptake inhibitors (SNRIs) for neuropathic pain modulation
• Anticonvulsants (e.g., gabapentin, pregabalin, carbamazepine) targeting ectopic neural discharge
• Muscle relaxants for associated myofascial hypertension

Interventional Management

Occipital Nerve Block

Peripheral nerve block of the GON and/or LON serves both diagnostic and therapeutic purposes. The procedure involves injection of a local anaesthetic agent (e.g., lignocaine or bupivacaine), typically combined with a corticosteroid, at the site of nerve emergence at the posterior cranial base. A 2023 systematic review and meta-analysis of 12 randomised controlled trials (586 participants) demonstrated statistically significant reductions in pain severity at 5–20 minutes, 1–6 weeks, and 12–24 weeks following occipital nerve block. Ultrasound guidance improves injection accuracy and is recommended where available.

Botulinum Toxin-A Injection

Botulinum toxin-A (BoNT-A) injection has been used as an alternative or adjunct to local anaesthetic nerve block. A retrospective series of 111 persons reported good or very good pain outcomes in 80% of cases at six months, a rate comparable to radiofrequency ablation, and with a favourable safety profile.

Surgical Management

Surgical intervention is reserved for persons with medically and procedurally refractory ON.

Occipital Nerve Stimulation

Occipital nerve stimulation (ONS) involves implantation of subcutaneous electrodes in proximity to the GON at the posterior cranial base. ONS has the strongest surgical evidence base for ON. Updated evidence-based guidelines from the Congress of Neurological Surgeons (2023), reviewing 18 studies, support its use in medically refractory ON. ONS has also been applied in refractory migraine, cluster headache, and cervicogenic headache.

Greater Occipital Nerve Decompression

Surgical decompression of the GON at anatomical sites of entrapment (semispinalis capitis, trapezius aponeurosis) is the most commonly studied decompressive procedure. A 2021 systematic review of 22 studies identified GON decompression as a useful treatment modality for medically refractory ON, reporting pain relief in approximately 62% of persons in one prospective cohort; however, randomised controlled trial data remain absent.

Dorsal Rhizotomy and Peripheral Neurectomy

Upper cervical dorsal rhizotomy (C1–C3) disrupts afferent nociceptive input but carries a risk of permanent scalp hypoaesthesia and does not uniformly produce pain relief. Peripheral neurectomy has demonstrated greater efficacy in larger cohorts; however, further high-quality studies are required to establish comparative effectiveness between these procedures.
