When light and sound become unbearable

Severe migraine with photophobia and phonophobia represents much more than a "bad headache." It is a complex neurologic disease that turns normal stimuli — the light of a lamp, the sound of a conversation — into intolerable assaults. During the attack, the patient seeks absolute darkness and silence, unable to work, care for children, or perform basic activities. It is a condition that steals entire days from one's life.

Preventive treatment of migraine is the fundamental pillar for restoring quality of life. Medical acupuncture for migraine prophylaxis has robust evidence (Cochrane) of efficacy comparable to preventive medications such as topiramate and beta-blockers in selected trials, with a generally more favorable adverse-effect profile \u2014 although acupuncture has its own risks (local discomfort, hematoma, vasovagal syncope, and, rarely, pneumothorax). Neuromodulation of the trigeminal and occipital territories can reduce the frequency, intensity, and duration of attacks, in addition to decreasing analgesic consumption.

How acupuncture modulates migraine

  1. Trigeminovascular system — the trigger of the attack

    Migraine begins with activation of the trigeminovascular system: trigeminal nerve fibers release vasoactive neuropeptides (CGRP, substance P) that promote neurogenic inflammation in the meninges. This cascade generates the characteristic unilateral pulsatile pain and sensitizes local receptors to normally painless stimuli.

  2. Central sensitization — photophobia and phonophobia

    Repeated activation of the trigeminal nerve sensitizes neurons of the brainstem (spinal trigeminal nucleus), which begin to interpret normal light and sound stimuli as painful. This central sensitization explains why light and sound become intolerable during the attack — and why frequent attacks progressively lower the firing threshold.

  3. Acupuncture neuromodulation in the occipital territory

    Stimulation of points such as GB-20 (fengchi) and BL-10 (tianzhu) in the suboccipital region activates afferent fibers that converge with the trigeminal in the trigeminocervical complex. This convergence allows acupuncture to directly modulate trigeminovascular processing, reducing central excitability and attack frequency.

  4. Endorphinergic and serotonergic effect

    Electroacupuncture at 2 Hz stimulates release of beta-endorphins and enkephalins, while a frequency of 15 Hz promotes release of dynorphin. Additionally, acupuncture modulates the serotonergic system — the same target as triptans — reducing CGRP release and normalizing meningeal vascular reactivity.

Myths about migraine and acupuncture

Myth vs. Fact

MYTH

Migraine is just a bad headache — everyone has it

FACT

Migraine is a genetic neurologic disease with documented changes in cortical excitability and the trigeminovascular system. It is classified by the WHO as one of the most disabling diseases in the world. Photophobia and phonophobia reflect real central sensitization — it is not exaggeration or low pain tolerance.

MYTH

Acupuncture for migraine has no scientific evidence

FACT

Acupuncture for migraine prevention has the highest level of evidence (1A) according to Cochrane, with multiple randomized clinical trials demonstrating efficacy comparable to traditional preventive medications, with fewer side effects. It is one of the indications with the best evidence in the practice of medical acupuncture.

MYTH

Taking analgesics when the attack comes is enough

FACT

Frequent use of analgesics (more than 10–15 days per month) causes medication-overuse headache — a paradoxical chronification that turns episodic migraine into daily. Preventive treatment with acupuncture reduces attack frequency and, consequently, the need for analgesics, breaking this cycle of chronification.

Treatment protocol

Assessment and headache diary
1st–2nd weeks

Classification of migraine (with or without aura, episodic or chronic), monthly frequency, intensity, identifiable triggers, current medications, and risk of medication-overuse headache. Initiation of headache diary for objective measurement. Exclusion of warning signs (secondary headache).

Cranial and cervical neuromodulation
Sessions 1–4 (weekly)

Base protocol: GB-20 (fengchi) bilateral, GB-8 (shuaigu) bilateral, EX-HN5 (taiyang), GV-20 (baihui). Distal points: LI-4 (hegu), LR-3 (taichong), GB-34 (yanglingquan). Electroacupuncture 2 Hz at suboccipital points. If associated cervical component: treatment of trigger points in the suboccipitals, SCM, and upper trapezius.

Intensification and protocol adjustment
Sessions 5–8 (weekly)

Reassessment of headache diary: frequency, intensity, and analgesic consumption. Adjustment of points according to clinical response. If associated menstrual migraine: perimenstrual acupuncture with points SP-6 and CV-4. Guidance on dietary triggers, sleep hygiene, and stress management.

Maintenance and spacing
From session 9

Transition to biweekly sessions for 2 months, then monthly for 3–6 months. Maintenance of results with periodic sessions. Quarterly reassessment of headache diary. If attacks < 4/month with good response, progressively space until discharge or quarterly maintenance.

Clinical pearl: cervicogenic migraine

Frequently Asked Questions

Yes. Acupuncture can be applied both preventively (between attacks) and abortively (during the attack). During acute attack, treatment focuses on analgesic points such as LI-4, EX-HN5 (taiyang), and GB-20. However, the greatest benefit of acupuncture is in prevention — reducing the frequency and intensity of attacks over time.

Acupuncture can be used as an isolated preventive treatment in migraines of moderate frequency, or in combination with medications in severe cases. Many patients manage to reduce or discontinue preventive medications after stabilization with acupuncture. The decision should be made together by the patient and the physician, based on individual clinical response.

Most patients begin to notice reduction in attack frequency and intensity after 4–6 weekly sessions. Full result is generally achieved in 8–12 sessions. Chronic migraines (more than 15 days/month) may require more sessions for stabilization. The headache diary is essential to document improvement objectively.

Menstrual migraine is linked to the drop in estrogen levels in the days preceding menstruation. This hormonal drop alters central serotonergic modulation, lowering the threshold for trigeminovascular activation. Perimenstrual acupuncture (3–5 days before menstruation) with points such as SP-6 and CV-4 can significantly reduce the frequency and intensity of menstrual attacks.
