When Headaches Start in the Neck

Headaches are often thought of as problems of the brain or blood vessels. But some headaches actually begin elsewhere — particularly in the neck and surrounding muscles. One such condition is cervicogenic headache (CGH), a type of headache that originates from dysfunction in the cervical spine and nearby soft tissues.

Recent research is shedding light on an intriguing possibility: the entire posterior myofascial chain, stretching from the base of the skull down the back to the calves, may play a role in these headaches.

The idea of a “posterior chain”

Therapists are familiar with the concept that muscles and fascia form interconnected chains across the body. The posterior myofascial chain links structures including:

• Suboccipital muscles and cervical extensors
• Upper trapezius and rhomboids
• Thoracolumbar fascia
• Gluteal and piriformis muscles
• Hamstrings and calf muscles

Tension or dysfunction in one part of this chain may influence mechanical stress elsewhere. In theory, tightness lower in the body could affect posture and spinal alignment, ultimately contributing to neck strain and headache.

A large clinical screening

To investigate this idea, researchers from India screened 1,283 people, identifying 188 individuals with cervicogenic headache using international diagnostic criteria.

The researchers examined two key features across the posterior chain:

1. Muscle tightness
2. Myofascial trigger points (TrPs)

Seventeen trigger point locations were assessed across the neck, back, and lower limbs. Muscle tightness was measured in structures such as the trapezius, thoracolumbar fascia, hamstrings, and calf muscles.

What they found

The results were striking.

People with cervicogenic headache showed very high levels of muscle tightness, especially in:

• Trapezius: ~97–99% of participants
• Thoracolumbar fascia: ~90%
• Hamstrings: ~95–98%

Trigger points were also common, particularly in:

• Occipital ridge: ~85%
• Lower cervical spine: ~91–97%
• Splenius capitis/cervicis: ~61–65%
• Rhomboids: ~53–55%

Statistical analysis showed these abnormalities were significantly higher than normal reference values.

Why the neck is only part of the story

Traditional thinking places cervicogenic headache primarily in the upper cervical region. That still appears to be true — muscles such as the trapezius, suboccipitals, splenius capitis, and sternocleidomastoid are frequently involved.

Trigger points in these muscles can refer pain to areas commonly associated with headaches:

• Upper trapezius: pain behind the eye
• SCM: pain in the forehead or temples
• Suboccipitals: pain at the base of the skull

But the new findings suggest that lower-body tissues may contribute indirectly.

For example:

• Hamstring tightness can alter pelvic alignment
• Thoracolumbar fascia tension affects spinal mechanics
• Calf and gluteal tension may influence posture and gait

These changes can propagate upward along the fascial chain, increasing mechanical stress in the cervical region.

A chain reaction of posture and tension

In many patients with cervicogenic headache, the problem may involve a feedback loop:

1. Cervical pain alters posture
2. Compensatory muscle tension develops down the posterior chain
3. Pelvic and spinal mechanics change
4. Cervical loading increases further
5. Headache symptoms persist or worsen

This perspective helps explain why some patients do not improve when treatment focuses only on the neck.

A unilateral condition

Another key feature of cervicogenic headache is that it is usually one-sided.

The study confirmed that:

• Muscle tightness and trigger points were significantly greater on the painful side of the body.

This aligns with clinical observations that unilateral musculoskeletal dysfunction — often involving the cervical spine or shoulder girdle — can drive CGH symptoms.

---

What this means for therapists

For manual therapists, physiotherapists, and movement practitioners, the findings reinforce an important principle:

The neck should not be treated in isolation.

Effective management may require assessment of the entire posterior chain, including:

• Upper trapezius and suboccipital muscles
• Thoracolumbar fascia
• Gluteal and piriformis muscles
• Hamstrings and calf muscles

Addressing myofascial tightness and trigger points throughout this chain may help reduce the mechanical drivers of cervicogenic headaches.

A note of caution

The study used a cross-sectional design, meaning all measurements were taken at one point in time. This makes it difficult to determine cause and effect. We cannot yet say whether posterior chain tightness causes headaches — or develops as a consequence of them.
