Why Neck Problems Can Be Connected to Headaches
Neck pain and headaches often occur together, but the reason is not always simply tight muscles. The cervical spine is a coordinated system of joints, discs, ligaments, muscles and nerves extending from the base of the skull into the upper back. Problems at different levels can create different patterns of pain.
Head pain that originates from structures in the neck is commonly called a cervicogenic headache. The upper cervical region is especially important because sensory information from the upper cervical nerves converges with trigeminal pathways involved in sensation from the head and face. This helps explain why irritation from upper cervical structures can sometimes be felt in the back of the head, temple, forehead or around the eye.
How the Upper Neck Moves: Occiput, C1 and C2
The head does not move as one solid unit on top of the seven cervical vertebrae. The occiput and upper cervical joints have specialized jobs. The occiput-C1 region contributes importantly to nodding, while C1-C2 provides a large portion of the neck’s axial rotation. Below that, the C2-C7 segments work together during flexion, extension, rotation and side bending.
Because normal neck motion is shared among multiple segments, restriction, degeneration or pain at one area can change how a person moves through the rest of the cervical spine.
Muscles and Nerves Around the Upper Cervical Spine
The suboccipital muscles, splenius capitis, sternocleidomastoid, scalenes, levator scapulae and upper trapezius all help stabilize or move the head, neck and shoulder region. When these tissues become irritated, tight or overworked, they can contribute to neck pain and restricted movement.
The greater occipital nerve arises primarily from the C2 spinal nerve and travels through the upper posterior neck to provide sensation to much of the back of the scalp. Irritation of this nerve, or of structures around its course, can contribute to pain in the upper neck and posterior head. This anatomy also helps patients understand why the location of head pain does not always identify the exact structure producing it.
The C2-3 Facet Joint and Cervicogenic Headache
The C2-3 facet joint deserves special attention when discussing headaches arising from the neck. Research on cervical facet pain has identified C2-3 as an important source of upper-neck and referred head pain. The joint is innervated in part by the third occipital nerve, and pain from this region can extend upward into the head.
This does not mean every headache comes from C2-3. Migraine, tension-type headache and other headache disorders can produce overlapping symptoms, and persistent, unusual or severe headaches require appropriate evaluation.
What Happens to the Facet Joints as We Age?
Facet joints are the small paired joints along the back of the cervical spine. They guide movement and help share load. Like other joints in the body, they can develop degenerative or arthritic changes over time. Cartilage and joint surfaces can change, osteophytes can develop, and joint mechanics can become less comfortable or less mobile.
In clinical studies of cervical facet-mediated pain, C2-3 and C5-6 are among the levels commonly implicated. Degenerative imaging findings are also common at several mid-cervical levels, including C3-4 and C4-5. This is why we pay close attention to the C4-5 and C5-6 region in patients with chronic neck pain, stiffness and reduced motion.
Importantly, arthritis on an X-ray or MRI does not automatically prove that a particular facet joint is causing someone’s symptoms. Degenerative findings become increasingly common with age and must be interpreted together with the history, examination, movement pattern and neurologic findings.
C4-5 and C5-6: Neck Pain, Stiffness and Referred Pain
Lower cervical facet irritation tends to produce a different referral pattern than upper cervical facet pain. C4-5 can refer discomfort into the lower neck and shoulder region, while C5-6 facet pain can extend toward the lower neck, upper shoulder and top of the shoulder blade. By contrast, C2-3 is much more closely associated with pain extending upward into the head.
A patient can also have more than one painful or degenerative region at the same time. For example, upper cervical dysfunction may contribute to headache while lower cervical degeneration contributes to persistent neck and shoulder pain.
Why We Also Examine the Thoracic Spine
The cervical spine does not function in isolation. The upper and mid-thoracic spine contribute to posture, extension and rotation of the trunk. If the thoracic region is stiff or a person spends long periods in a flexed posture, the neck may need to compensate during everyday activities such as looking forward, turning the head, working at a computer or driving.
Research supports considering the thoracic region as part of conservative management for some people with mechanical neck pain. That does not mean the thoracic spine is the cause of every neck problem; it means examining the entire cervical-thoracic movement system can provide a more complete picture.
How We Evaluate Neck Pain and Headaches at The Healing Joint
At The Healing Joint in Scottsdale, our goal is to determine which structures and movement patterns appear most relevant rather than assuming every patient has the same problem. An evaluation may include cervical and thoracic range of motion, posture, joint mobility, muscle and soft-tissue findings, neurologic screening and review of available imaging when clinically appropriate.
Depending on the findings and the patient’s needs, conservative care may include chiropractic manipulation or mobilization when appropriate, Active Release Technique and other soft-tissue work, Class IV laser therapy, acupuncture, assisted stretching and individualized home exercises. For additional guidance, visit Dr. D’s Head & Neck Exercise Library. Cervical spinal decompression may also be considered for selected patients when the examination and clinical picture support its use. The exact combination is based on the examination rather than a one-size-fits-all protocol.

Cervical Spinal Decompression
For selected patients with chronic neck pain and degenerative changes, including changes around C4–5 or C5–6, cervical spinal decompression may be considered as one component of a broader treatment plan. Facet-joint arthritis or degeneration seen on imaging does not by itself determine whether decompression is appropriate; symptoms, examination findings, neurologic status and the overall clinical picture should guide treatment.
When a Headache Needs Medical Attention
Not every headache should be treated as a musculoskeletal problem. New or sudden severe headache, headache following significant trauma, or headache accompanied by neurologic symptoms, fever, confusion, fainting, vision changes or other concerning symptoms warrants prompt medical evaluation.
