Migraine is a prevalent neurological condition characterized by intense, throbbing, unilateral cranial pain. Clinically, it is defined by three hallmark features: abrupt onset of severe one-sided headache, spontaneous or pharmacologically assisted pain resolution with no residual neurological sequelae, and recurrent symptomatic episodes separated by pain-free intervals. As a periodic vascular headache disorder, migraine significantly impairs patients’ quality of life, daily functioning, and mental well-being across all age groups worldwide.
The pathophysiology of migraine involves distinct cerebrovascular dynamic changes. In the early phase of a migraine attack, intracranial arterial vasoconstriction leads to focal ischemia in corresponding cerebral perfusion areas. This vasoconstrictive phase is subsequently followed by extracranial arterial vasodilation, which triggers the severe throbbing pain typical of migraine episodes.
Biochemical research confirms that migraine onset is closely associated with abnormal blood levels of serotonin, bradykinin, and prostaglandins, as well as altered platelet monoamine oxidase activity. Furthermore, genetic susceptibility and endocrine dysfunction serve as major pathogenic contributors. Common triggering factors include physical overexertion, persistent mental stress, depression, anxiety disorders, consumption of tyramine-rich foods, and excessive alcohol consumption.
Clinical Diagnostic Criteria for Migraine
Migraine can manifest at any age. Its prevalence gradually increases from childhood, peaks between 30 and 50 years of age, and slowly declines in later adulthood. The initial onset of migraine most frequently occurs in patients aged 20 to 30 years. Over 50 percent of migraine patients have a positive familial genetic history. The primary clinical manifestations of migraine are paroxysmal onset, spontaneous symptomatic remission, and high recurrence tendency.
Classic migraine episodes are divided into four standardized clinical stages:
1. Prodromal Stage
This stage occurs approximately 30 minutes prior to headache onset. Typical prodromal symptoms include scintillating scotoma presenting in the visual field contralateral to the painful side of the head, progressive enlargement of visual blind spots, and occasional homonymous hemianopia. Patients may also experience generalized malaise, mild speech impairment, numbness of the lips and fingertips, dizziness, pallor, polyuria, and other mild systemic symptoms.
2. Headache Onset Stage
Once prodromal symptoms subside, patients experience sudden throbbing headache, predominantly localized to the unilateral forehead or parietal region.
3. Peak Headache Stage
Pain intensity reaches its peak during this stage, spreading progressively from the unilateral forehead to the orbital cavity and vertex, often accompanied by retro-orbital pain. The pain gradually intensifies and is commonly associated with nausea and vomiting. After lasting approximately 2 to 3 hours, symptoms gradually alleviate.
4. Post-Headache Recovery Stage
Headache symptoms gradually resolve during the recovery phase, with most patients experiencing significant drowsiness. Some individuals may present transient euphoria, excitement, or a hollow cranial sensation.
Migraine intervals and recurrence frequency vary significantly among individuals. Episodic flare-ups are primarily triggered by psychological stress, endocrine imbalances, dietary irregularities, and unfavorable environmental stimuli. Attack frequency ranges from multiple episodes daily to a single episode every several months.
Standard Acupuncture Treatment for Migraine
Acupuncture for migraine is a safe, evidence-based natural TCM intervention with rapid analgesic effects. Standardized acupoint stimulation corrects neurological and vascular dysfunction at the source, delivering stable, long-term relief for recurrent migraine disorders.
Core Acupoints & Standard Needling Methods (WHO Standard Codes)
1. Taiyang (EX-HN5, Affected Side)
Location: A hollow depression roughly 25 mm posterior to the midpoint between the lateral eyebrow tip and the outer canthus. Needling method: Use a 30-gauge, 2-inch filiform needle. After standard aseptic disinfection, insert the needle obliquely to a depth of 45 mm toward the Shuaigu (GB8) acupoint. Needling sensation: Temporal distension and soreness.
2. Shuaigu (GB8, Affected Side)
Location: 40 mm vertically above the ear apex, within the hairline. Needling method: Use a 30-gauge, 1.5-inch filiform needle. After local disinfection, perform horizontal subcutaneous insertion to a depth of 35 mm toward the occipital region. Needling sensation: Local distending soreness.
3. Baihui (GV20)
Location: Located at the cranial midline depression, approximately 90 mm above the posterior hairline midpoint, on the vertical line connecting bilateral ear apexes. Needling method: Use a 30-gauge, 1-inch filiform needle. After disinfection, insert the needle obliquely backward to a depth of 15 mm until contacting the cranial periosteum. Needling sensation: Local cranial distension and soreness.
4. Fengchi (GB20, Affected Side)
Location: The hollow depression between the upper attachments of the sternocleidomastoid and trapezius muscles, level with the Fengfu (GV16) acupoint. Needling method: Use a 30-gauge, 2-inch filiform needle. After routine aseptic disinfection, insert the needle obliquely 40 mm toward the spinal column. Needling sensation: Local cervical soreness and distension, or radiating tingling and fullness extending to the ipsilateral temporal and parietal areas.
Complete Treatment Protocol
Patients are treated in a seated position. All targeted acupoints are needled following standardized aseptic techniques. Needles are retained for 40 minutes per session, with one round of manual reinforcing and reducing manipulation performed at the 20-minute mark during retention to enhance therapeutic stimulation.
Treatment is administered once daily. A full therapeutic course consists of six consecutive sessions. Intervention can be initiated immediately during acute migraine flares or continued intermittently once every three days for long-term preventive conditioning.
Clinical Notes & Therapeutic Effect Analysis
TCM acupuncture yields precise and reliable therapeutic effects for migraine management. Most patients achieve substantial pain relief or complete symptomatic resolution within 10 minutes post-insertion. It is common for patients to discontinue treatment prematurely once pain subsides. However, completion of the full six-session course is clinically critical. Standard full-course acupuncture effectively prolongs migraine remission intervals and reduces pain severity during subsequent episodes.
For patients with recurrent migraine, immediate acupuncture intervention at the earliest onset of symptoms is highly recommended. Consistent, standardized treatment gradually reduces migraine frequency and prevents long-term recurrent flares.
Patients presenting with no symptomatic improvement or aggravated pain after one full acupuncture course require comprehensive clinical re-evaluation. Further diagnostic testing is necessary to confirm the accurate etiology and underlying primary condition, ensuring targeted and effective clinical intervention.
