Occipital neuralgia was for many years known as Arnold's disease. However, the name is controversial. It is unclear whether the eponym refers to Julius Arnold, known for describing a congenital structural malformation of the posterior cranial fossa (the Arnold-Chiari malformation), or to his father, Friedrich Arnold.
Interestingly, the first clinical description of occipital neuralgia was made as early as 1821 by Spanish physicians José Benito and Mateo Martínez. They published a 24-page paper in *Décadas médico-quirúrgicas y farmacéuticas*, describing a patient with severe, tearing pain radiating from the C1–C2 space to the occiput. The designations C1, C2, and C3 refer to the first three cervical vertebrae — the topmost "building blocks" of the neck, located directly beneath the base of the skull. The nerves responsible for sensation in the back of the head emerge from the level of the second and third cervical vertebrae, which is why irritation of structures in this area can cause pain radiating from the upper neck toward the occiput and even toward the top of the head.
The chronology clearly shows that the Arnolds could not have been the first to describe this condition — yet the name "Arnold's disease" persists in the medical literature to this day.
What is occipital neuralgia?
Occipital neuralgia is a paroxysmal, piercing pain localized in the back of the head, in the territory innervated by:
- The greater occipital nerve
- The lesser occipital nerve
- The third occipital nerve
It is a relatively rare cause of headache, but exceptionally distressing and frequently confused with migraine or cervicogenic headache.
Anatomical basis
Greater occipital nerve (C2)
Most commonly responsible for symptoms. It emerges between the atlas (C1) and axis (C2), pierces the semispinalis capitis muscle and the trapezius tendon, runs alongside the occipital artery, and innervates the skin of the occiput and partially the vertex. Its exit point is approximately 2 cm from the midline and 2–3 cm below the external occipital protuberance — this point is often tender on palpation and used for diagnostic nerve blocks.
Lesser occipital nerve (C2–C3)
A branch of the cervical plexus. It courses along the posterior border of the sternocleidomastoid muscle and innervates the posterior aspect of the ear and the temporal-occipital area.
Third occipital nerve (C3)
A dorsal branch of C3 that may connect with the greater occipital nerve, forming the posterior cervical plexus.
Clinical symptoms
Occipital neuralgia is characterized by:
- Sudden, "electric" pain
- Piercing or tearing quality
- Paroxysms lasting from seconds to minutes
- Often unilateral onset
Possible accompanying symptoms:
- Scalp allodynia (pain when brushing hair)
- Tenderness over the nerve
- Dizziness
- Nausea
- Tinnitus
- Eye pain
Pain may radiate to the frontal region due to connections with the spinal nucleus of the trigeminal nerve.
Epidemiology
Occipital neuralgia is a rare condition:
- Incidence: approximately 3 per 100,000
- Mean age of onset: approximately 54–56 years
- Female predominance observed in studies (up to ~79%)
- Diagnosis is often delayed by 2–4 years
Pathogenesis — what causes occipital neuralgia
Causes can be divided into four groups:
1. Mechanical nerve compression
- Entrapment in the semispinalis muscle
- Trapezius muscle tension
- Poor posture
2. Vascular causes
- Compression by a blood vessel
- Giant cell arteritis
3. Neurogenic causes
- Neuromas
- Myelitis
- Multiple sclerosis
4. Structural changes
- Cervical spine degeneration
- C1 hypermobility
- Neoplastic processes
- Post-traumatic sequelae
Diagnosis
The foundation is clinical examination:
- Tenderness at the nerve exit point
- Tinel's sign
- Paroxysmal character of pain
Ancillary studies:
- Cervical spine X-ray
- CT (assessment of bony changes)
- MRI (method of choice — soft tissues + nerve roots)
- Ultrasound of nerve course
- Diagnostic nerve block
Differential diagnosis
Must be excluded:
- Migraine
- Cluster headache
- Tension-type headache
- Cervicogenic headache
- C2 radiculopathy
- Neoplastic processes
- Craniocervical malformations
Treatment of occipital neuralgia
1. Non-pharmacological treatment
- Physical therapy
- Manual therapy
- Paraspinal muscle massage
- TENS
- Acupuncture
- Posture correction
2. Pharmacological treatment
- Analgesics, NSAIDs, acetaminophen
- Tricyclic antidepressants (amitriptyline, nortriptyline)
- Antiepileptic drugs (gabapentin, pregabalin, carbamazepine, oxcarbazepine)
- SNRIs (duloxetine, venlafaxine)
3. Occipital nerve blocks
Administration of:
- Lidocaine
- Bupivacaine
- ± corticosteroid
Effects may last from weeks to several months.
4. Interventional treatment
- Radiofrequency ablation
- Cryoneurolysis
- Occipital nerve stimulation
- C2 gangliotomy
- Surgical decompression
Surgical decompression is considered a "last resort" and qualification requires thorough neurological workup and exclusion of other pain causes.
Summary
Occipital neuralgia is a rare but very painful form of neuropathic headache.
It is characterized by:
- Sudden paroxysms of piercing pain
- Tenderness at the nerve exit point
- Good response to diagnostic nerve block
Proper diagnosis allows avoidance of years of ineffective "migraine" treatment and enables targeted therapy — from physical therapy to pharmacological treatment to neuromodulation procedures.
Do you recognize these symptoms — sudden, piercing pain in the back of the head, tenderness to touch, pain worsening with neck movements? Have you been diagnosed with occipital neuralgia? What treatment was used, and did it bring relief?

Frequently Asked Questions
What is trigeminal neuralgia?
Trigeminal neuralgia is a chronic facial pain condition. It manifests as sudden, severe, usually one-sided pain attacks — often described as an electric shock. A single attack typically lasts from a few seconds to about two minutes.
What is the difference between neuralgia and neuropathy?
In simple terms: neuralgia primarily involves paroxysmal pain along a nerve, usually without loss of sensation. Neuropathy involves nerve damage that more often causes constant pain along with numbness and sensory loss.
Do regular painkillers help with neuropathic pain?
Usually not. Neuropathic pain responds poorly to paracetamol or anti-inflammatory drugs. Instead, medications that act on nerves are used, such as anticonvulsants like carbamazepine.
How does carbamazepine work for trigeminal neuralgia?
Carbamazepine is the first-line medication for trigeminal neuralgia. In a large proportion of patients, it provides effective pain control. It requires gradual dose adjustment and medical supervision.
What is the difference between gabapentin and pregabalin?
Both are anticonvulsant medications used for neuropathic pain. They differ in absorption and dosing characteristics. The choice and dosage should be determined by a physician.
