Headaches are extremely common, but not all headaches have the same cause.
Some are associated with stress, dehydration, lack of sleep or migraine. Others may be linked to problems in the neck.
When a headache is related to structures in the cervical spine, it is often referred to as a cervicogenic headache.
These headaches can be confusing because the pain is usually felt in the head, even though the source may be somewhere else.
Understanding the connection between the neck and headaches can help people recognise when neck function may be contributing to their symptoms.
How can the neck cause a headache?
Table of Contents
The upper part of the neck contains joints, muscles and nerves that share neurological connections with areas of the head.
Because of these shared pathways, irritation or dysfunction in the upper cervical spine can sometimes be experienced as pain in the head.
This is known as referred pain.
In other words, the place where pain is felt is not always the place where it originates.
A person may therefore experience pain around the back of the head, temple, forehead or behind the eye even when the contributing problem is in the neck.
What does a neck-related headache feel like?
Cervicogenic headaches can vary from person to person, but some common features may include:
- headache associated with neck pain or stiffness
- pain that begins at the back of the head and travels forward
- pain that is stronger on one side
- headache triggered by neck movement
- reduced neck mobility
- tenderness around the upper neck
- pain after prolonged desk work or poor positioning
- symptoms that worsen after holding the head in one position for a long time
Unlike migraine, cervicogenic headaches are usually linked more closely to mechanical factors involving the neck.
That said, symptoms can overlap, so headaches should not be self-diagnosed based on one feature alone.
Why does desk work sometimes trigger headaches?
Long periods of computer work can place sustained demands on the muscles and joints of the neck.
Many people spend hours each day looking at a screen with relatively little movement.
Over time, this can contribute to:
- neck stiffness
- muscle fatigue
- reduced movement
- tension around the shoulders
- discomfort at the base of the skull
These changes may contribute to headache symptoms in some people.
The issue is not necessarily one single “bad posture”.
More often, it is the combination of prolonged positioning, low movement variety and muscular fatigue.
Headaches can have many different causes, and in some cases neck function may be one of the contributing factors. Sydney Chiropractic in Marrickville works with people experiencing neck pain, headaches and related musculoskeletal concerns.
Is posture really the problem?
Posture is often blamed for neck pain and headaches, but the issue is usually more complex.
There is no single perfect posture that everyone should maintain all day.
People naturally sit and move in different ways.
A more useful focus is often on movement variation.
Changing position regularly, taking short breaks and avoiding long periods in one fixed posture can be more practical than trying to sit perfectly for hours.
For desk workers, small changes can make a meaningful difference.
These might include:
- adjusting screen height
- bringing the monitor closer
- relaxing the shoulders
- taking regular movement breaks
- alternating between sitting and standing
- turning the head and neck through comfortable ranges during the day
Can tight muscles cause headaches?
Muscle tension can contribute to headache symptoms.
Muscles around the neck, shoulders and upper back can become sensitive or fatigued, particularly during stressful periods or after prolonged computer use.
Common areas include:
- upper trapezius
- suboccipital muscles
- levator scapulae
- muscles around the shoulder blade
Tension in these areas does not always mean the muscle itself is the only cause of the headache.
Often, muscle discomfort is part of a wider pattern involving movement, workload, stress and neck function.
What about stress?
Stress can play a significant role in both neck pain and headaches.
When people are stressed, they may:
- clench their jaw
- raise their shoulders
- sleep poorly
- move less
- spend longer periods working
- become more sensitive to pain
This can create a cycle in which stress contributes to physical tension, which then contributes to discomfort.
Managing headaches effectively may therefore involve more than simply treating one painful area.
Sleep, workload, exercise and general recovery can all matter.
How are neck-related headaches assessed?
An assessment usually begins with a detailed history.
A health professional may ask:
- where the headache starts
- where the pain travels
- how often it occurs
- whether neck movement affects it
- whether there is associated neck pain
- what activities trigger symptoms
- whether there are visual symptoms, nausea or dizziness
- whether there has been recent injury or trauma
The physical assessment may then look at:
- neck movement
- joint mobility
- muscle tenderness
- posture and movement patterns
- strength
- neurological function
The aim is to understand whether the neck is likely to be contributing to the headache or whether another cause should be considered.
Can treatment help?
If the headache is genuinely related to the neck, management may focus on improving neck function and reducing contributing factors.
This can include:
- improving mobility
- strengthening the neck and upper back
- manual therapy
- exercise
- improving desk setup
- changing movement habits
- reducing prolonged static positions
The exact approach depends on the individual.
There is no single treatment that is right for every headache.
When should headaches be investigated urgently?
Most headaches are not caused by serious conditions.
However, some symptoms require prompt medical assessment.
Seek urgent medical care if a headache:
- starts suddenly and is extremely severe
- follows significant head or neck trauma
- is associated with weakness, numbness or difficulty speaking
- occurs with fainting or loss of consciousness
- is accompanied by fever and neck stiffness
- is associated with new visual changes
- becomes progressively worse without explanation
- is very different from previous headaches
A new or unusual headache should be assessed appropriately rather than assumed to be coming from the neck.
What can you do if your headaches seem linked to your neck?
If headaches tend to occur after long periods at a desk, during periods of neck stiffness, or alongside reduced neck movement, it may be worth paying attention to the pattern.
Simple steps can include:
- moving more regularly
- taking breaks from screens
- changing sitting positions
- maintaining regular exercise
- working on neck and upper-back strength
- improving sleep and recovery
- reducing prolonged positions that trigger symptoms
If the headaches keep returning, getting them assessed can help clarify whether the neck is likely to be contributing.
The key point
Headaches can have many different causes.
In some cases, the neck may be one of the contributing factors.
Because the structures of the upper neck and head share neurological connections, problems in the cervical spine can sometimes produce referred pain that feels like a headache.
The most useful approach is not to assume all headaches are the same.
Instead, look at the pattern, the triggers and the associated symptoms.
If headaches are recurring, changing, or interfering with daily life, a proper assessment can help determine what may be contributing and what steps are appropriate.
