Tension Headaches and Cluster Headaches Relief: Trapezius and SCM Release
Trapezius–Sternocleidomastoid Complex
This modality teaches the release of the Trapezius–Sternocleidomastoid Complex, two major muscles responsible for stabilizing the head and shoulders. Chronic spasm in this system can produce neck pain, headaches, and restricted movement of the cervical spine.

Step 1
Understanding the Problem
The trapezius and the sternocleidomastoid hold the head up against gravity all day, every day, and both attach at the mastoid bone behind the ear and along the base of the skull. Constant anti-gravity work, stress and repetitive posture fatigue them into a spasm that does not let go. The result is the headache that wraps around the head like a band, the cluster of pain behind one eye and temple, tenderness behind the ear, aching at the back of the skull, and a neck and shoulders that never fully relax. Releasology releases the trapezius and SCM directly, at the muscles and at their skull attachments, so the head can finally rest in neutral.
What this release relieves
- Tension headaches. The band-like headache across the forehead and temples is referred from trapezius and SCM in spasm. Clients describe it lifting as the muscles release.
- Cluster headaches and pain behind one eye. The SCM refers pain into the eye, temple and forehead on the same side. When the cluster pattern follows that path, the muscle is the place to look.
- Mastoid tenderness and pain behind the ear. Both muscles attach at the mastoid; tenderness there is their pull on the bone, and it eases as they release.
- Aching at the base of the skull and occipital inflammation. The upper trapezius attaches along the occiput. Its spasm keeps the back of the head inflamed and sore.
- Neck and shoulder tightness and fatigue from holding the head up. Clients describe not being able to find a comfortable head position; that is the anti-gravity muscles locked. Neutral returns when they release.
- Restricted neck movement. Turning, tilting and looking up are all limited by these two muscles in spasm.
The trapezius and sternocleidomastoid (SCM) are not typically the root cause of complex dysfunction, but when they enter spasm, they create a persistent and often overlooked pattern of imbalance.
Clients rarely present with sharp, localized pain in these muscles. Instead, they describe:a constant achetightness through the neck and shouldersfatigue from holding the head upright
These muscles act as positional stabilizers.
When they lose the ability to relax, the body reorganizes around them.
The result is not collapse, but compensation—a system that is held in place rather than freely balanced.
Frequently asked questions
How is this different from the migraine release?
Migraines (Modality 03) trace to the scalenus anterior compressing the vessels to the head. Tension and cluster headaches trace to the trapezius and SCM referring pain into the head. The history and the pain pattern tell which it is, and both can be released.
Can a neck muscle really cause a headache behind my eye?
Yes. The sternocleidomastoid refers pain into the eye, forehead and temple on the same side; that referral pattern has been documented for decades. Releasing the muscle stops the referral.
How quickly does it work?
Many clients feel the head lighten and the headache soften during the first session. Chronic patterns take a short series, and the modality teaches a self-release to use at the first sign of a headache.
Step 2
The Clinical Problem
Clinically, trapezius and SCM spasm presents as a chronic, diffuse pattern of tension rather than an acute injury.
Common findings for SCM include:
-
persistent aching in the mastoid process and upper shoulders
-
weakness and mastoid headache while looking up
-
inability to rotate the head toward this muscle when it is in spasm
-
restricted ability to look downward
-
tenderness at the mastoid process
-
fatigue associated with maintaining head posture
-
subtly lifting and extending the head
-
restricting flexion at the upper cervical spine
-
producing localized pain at the mastoid during attempted downward movement
And, for trapezius include:
-
persistant aching, inflammation and palpable tension in the very back of the occipital bone.
-
scoliotic curve along the entire origin of the trapezius (Occipital bone, C7 to T12)
-
the levator scapulae lifts the inside of the scapula bone, but when the outside of the scapula bone, along with the scapula, are elevated, we know the trapezius is in spasm
-
the vertebral column appears to roll toward the side of contraction
-
the spinous processes rotate ipsilaterally
-
the entire system adopts a biased resting position
This combination creates a pattern where the client is not only in discomfort, but is mechanically unable to settle into a neutral position.
This is why many symptoms that appear to originate in the back of the head - from the occipital bone to the mastoid process of the temporal bone, actually arise from spasm of the Trapezius and SCM.
Step 3
Why This Happens
These patterns arise because the trapezius and SCM are constantly active in maintaining the position of the head against gravity.
Unlike many muscles that work intermittently, these muscles are engaged throughout the day to stabilize:
-
head position
-
gaze orientation
-
shoulder and upper spinal alignment
When fatigue, stress, or repetitive postural demands are introduced, these muscles can enter a state of involuntary contraction.
Once in spasm:
-
the Trapezius begins to anchor the shoulder and upper spine, pulling the system toward one side
-
the SCM maintains a subtle lifting and extension of the head, resisting downward movement
Because these muscles operate at a global level, their contraction does not remain isolated. Instead, it is distributed across the entire system.
The trapezius, due to its size and attachments, can influence the orientation of the vertebral column, creating the observed ipsilateral rotation and spinal roll.
The SCM, due to its attachment at the mastoid, introduces tension at the cranial base, particularly during attempts to extend the neck.
From a Releasology perspective, this represents a disruption in conduction.
A muscle in spasm behaves as a point of resistance within the system. Instead of transmitting force smoothly, it absorbs and redirects it, creating asymmetry.
As this resistance persists:
-
movement becomes restricted
-
effort increases
-
awareness narrows
The system adapts around the restriction, reinforcing the pattern over time.
