The most common headache in the world

Tension-type headache affects up to 78% of the population over the lifetime and is the leading cause of pain-related productivity loss in the Western world. The characteristic sensation of a "band" or "helmet" tightening around the head bilaterally distinguishes this type of headache from migraine — which is generally unilateral, pulsatile, and accompanied by nausea.

Although the name "tension" suggests a psychological cause, tension-type headache has a clearly defined muscular and neurologic basis. Chronic tension in the suboccipital, upper trapezius, sternocleidomastoid (SCM), and temporalis muscles — perpetuated by inadequate posture, stress, and sleep deprivation — activates trigger points that refer band-like pain across the cranial vault.

MORE IN WOMEN
chronic tension-type headache is twice as prevalent in women, possibly due to hormonal and muscular factors

Mechanism: from muscle tension to band-like headache

  1. Postural load

    Screen posture, stress, and emotional tension chronically raise the tone of the trapezius, SCM, and temporalis.

  2. Craniocervical trigger points

    Upper trapezius refers "star-shaped" pain to the head; SCM causes vertex and forehead pain; temporalis refers pain to the temples.

  3. Peripheral sensitization

    Active trigger points release substance P and CGRP, sensitizing pericranial nociceptors — hence allodynia when combing the hair.

  4. Trigeminocervical convergence

    Inputs from cervical muscles (C1-C3) converge with the trigeminal nerve in the brainstem, producing diffuse band-like pain.

  5. Needling and resolution

    Acupuncture at muscle trigger points and at GB-20, GV-20, BL-10 deactivates the peripheral source and modulates central processing.

Medical treatment protocol

Assessment
1st visit

Headache diary (frequency, intensity, triggers). Trigger point palpation: trapezius, SCM, temporalis, suboccipitals, frontalis. Differentiation from migraine and mixed headache.

Initial phase
Sessions 1–4

Needling at LI-4, LR-3 (classic analgesic pair) and GB-20 for immediate relief. Suboccipitals if tolerated. 2–3 sessions/week in the acute phase.

Focal muscular phase
Sessions 5–9

Needling of all active craniocervical trigger points: trapezius, SCM, temporalis, masseter. 2 Hz cervical electroacupuncture. Cranial technique if indicated.

Preventive maintenance
Monthly

Reduction to monthly maintenance sessions. Headache diary review. Guidance on sleep hygiene, hydration, and stress management.

  5. 05

    Associated with stress, sleep deprivation, or prolonged posture

  7. 07

    Partial improvement with common analgesics (but tends to chronify with overuse)

Myths and facts

Myth vs. Fact

MYTH

Tension-type headache is "stress" and has no physical treatment

FACT

Tension-type headache has a concrete muscular substrate — active trigger points in the trapezius, SCM, and temporalis. The emotional component amplifies, but the primary cause is muscular and responds to physical treatment.

MYTH

Acupuncture works only as a placebo for headache

FACT

The Cochrane review (Linde et al.) concluded that acupuncture may be at least comparable to conventional prophylactic treatments for frequent tension-type headache, with a favorable adverse-event profile. Plausible neurobiologic mechanisms are under investigation — it is not merely placebo, although the debate around sham acupuncture continues.

MYTH

I need to take preventive medication every day to control the headache

FACT

Clinical trials of acupuncture for tension-type headache describe relevant reductions in attack frequency in a significant proportion of patients after a treatment cycle (magnitude variable across studies). For some patients, it may allow reduction of pharmacologic prophylaxis — an individualized decision, coordinated with the responsible physician.

Frequently Asked Questions

Some comparative trials suggest that acupuncture may have an effect of magnitude close to that of prophylactics such as amitriptyline in chronic tension-type headache, with a typically more favorable adverse-event profile — the evidence base is still limited and heterogeneous. Acupuncture does not induce drowsiness, weight gain, or dependency, but the therapeutic choice should be individualized by the physician.

Yes, especially in the first weeks when the effects of acupuncture are still consolidating. The goal is to progressively reduce analgesic use over the course of the treatment cycle — not to stop them abruptly.

Yes — this is called mixed headache or combined headache. It is common: the person has a baseline of frequent tension-type headache on which more intense migraine attacks occur. Medical acupuncture treats both components and frequently reduces both the baseline frequency and the intensity of migraine attacks.

Most patients report pain reduction during or shortly after the first 2–3 sessions. The prophylactic effect — reduction in attack frequency — consolidates after 4–6 weeks of regular treatment.
