Headache is one of the most common complaints in modern life. Most people associate it primarily with migraine, tension, or stress. However, there is a particular type of headache whose source is not in the head at all, but in the structures of the neck.
This relatively little-known medical problem is called cervicogenic headache (CGH). Although it occurs less frequently than migraine or tension-type headache, it can significantly reduce quality of life and is often difficult to diagnose correctly.
What is cervicogenic headache?
Cervicogenic headache is a pain syndrome in which the primary source of symptoms is located in the structures of the cervical spine. These may include:
- Facet joints
- Intervertebral discs
- Neck muscles
- Ligaments
- Cervical nerve roots
A characteristic feature of this pain is that it starts in the neck area and only then radiates to other parts of the head. It most commonly involves:
- The occiput
- The temple
- The parietal region
- The forehead
- Sometimes even the orbital area
Unlike migraine, this pain is usually dull, deep, and non-pulsating. In most patients, it appears on one side and remains on the same side of the head for extended periods.
History of discovery
Although cervicogenic headache is relatively well-described today, its history only dates back to the mid-twentieth century. The first observations appeared in 1949, when American neurosurgeons Cedric Hunter and Frederic Mayfield described a group of patients with atypical headache that was effectively treated with cervical nerve blocks.
Their discovery remained on the margins of medicine for a long time. It was not until the 1980s that Norwegian neurologist Ottar Sjaastad proposed the term "cervicogenic headache" and provided a detailed description of the condition's symptoms.
From that point on, intensive research into its mechanisms and treatment began.
How common is cervicogenic headache?
The exact prevalence is not easy to establish. Estimates suggest:
- In the general population, it affects approximately 1–4% of people
- Among individuals with chronic headaches, it may account for up to 15–20% of cases
It most commonly appears between ages 30 and 40, though it can also occur in younger people and even children. Many specialists believe the condition is underdiagnosed because it is frequently confused with other headache types.
Why the neck can cause headache
The key to understanding this phenomenon lies in the anatomy of the nervous system. In the upper spinal cord, there are connections between sensory fibers of the cervical nerves and structures responsible for receiving pain signals from the head and face.
This means that pain impulses originating from the neck can be interpreted by the brain as headache. This mechanism is called sensory convergence.
In practice, it means that damage to or irritation of cervical structures — even relatively minor — can cause pain felt in an entirely different location.
Most common causes
One of the most common causes of cervicogenic headache is dysfunction of the facet joints in the upper cervical spine, particularly at the C2–C3 level.
Other important contributing factors include:
- Cervical spine injuries
- Degenerative changes
- Disc disease
- Congenital spinal anomalies
Particular attention is paid to whiplash injury. This occurs most often in car collisions, when the head is rapidly thrown backward and forward. Even if imaging studies show no serious damage, such an injury can lead to chronic neck and head pain.
Symptoms that can mislead
The symptoms of cervicogenic headache can be confusing because they resemble other neurological conditions.
Most common symptoms include:
- Neck pain
- Restricted neck mobility
- Unilateral headache
- Worsening of pain with head movements
Sometimes migraine-like symptoms also appear:
- Nausea
- Vomiting
- Photophobia
- Sound sensitivity
- Dizziness
This is exactly why many patients are treated for migraine or tension-type headache for years before the correct diagnosis is made.
How physicians diagnose the condition
The foundation of diagnosis is a thorough medical history and neurological examination. The physician pays particular attention to:
- When the pain appeared
- Its location
- Its relationship to neck movements
Imaging studies such as MRI or CT are not always helpful, because similar cervical spine changes can occur in people without pain.
The most characteristic diagnostic test is a cervical nerve block. It involves injecting a small amount of anesthetic in the C2–C3 nerve area. If the pain resolves, this confirms its cervical origin.
Treatment — why it must be multimodal
Treatment of cervicogenic headache is typically multifaceted and involves several methods simultaneously.
Pharmacological treatment
Commonly used medications include:
- Nonsteroidal anti-inflammatory drugs
- Antiepileptic drugs
- Antidepressants
- Muscle relaxants
Unfortunately, medications alone often provide only limited relief.
Physical therapy
Exercises improving cervical spine mobility and strengthening neck muscles can significantly reduce symptoms.
Nerve blocks
One of the most effective methods is anesthetic blockade of cervical nerves. In addition to its diagnostic function, it can provide relief for weeks or even months.
Interventional procedures
In some patients, procedures such as high-frequency neurolysis are used, which involves controlled disruption of pain-conducting nerve fibers.
Surgical treatment
In very severe cases, surgical procedures such as nerve root decompression may be performed.
Impact on quality of life
Although cervicogenic headache is not a life-threatening condition, its impact on patients' lives can be substantial. Chronic pain interferes with work, limits physical activity, and worsens psychological well-being. Research shows that quality of life in people with this condition is often reduced similarly to that of migraine patients.
Awareness of cervicogenic headache is important for both physicians and patients. A correct diagnosis allows for more effective treatment and avoids years of taking medications that provide no meaningful improvement.
In many cases, the source of pain is not where we feel it. Sometimes the key to solving the headache problem turns out to be... the neck.

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.
Why is an MRI performed?
MRI helps detect neurovascular conflict and rule out other causes of pain, such as tumors or multiple sclerosis. The diagnosis of neuralgia itself is primarily clinical.
Which doctor should I see for facial pain?
First, see a neurologist. If surgery is being considered, a neurosurgeon. If a dental cause is suspected, it is also worth ruling it out with a dentist.
Can trigeminal neuralgia be cured?
In many people, pain can be effectively controlled with medications or procedures, and MVD provides the most durable results in eligible patients. The course varies — with periods of remission and relapse. Decisions are made together with your doctor.
What is guided imagery and can it help with pain?
Guided imagery (visualization) is a relaxation technique where you use imagination to mentally visit a calm, safe place. Research shows it can lower stress, calm the nervous system, and reduce pain perception — especially helpful for chronic facial pain.
