Migraines affect roughly 8% of Canadians. They're not just bad headaches — they involve a cascade of neurological changes that can last hours or days, and they're notoriously difficult to treat reliably. Medication works for many people; for others it doesn't, or the side effects are a problem.
So where does acupressure fit? The honest answer: it's a reasonable supportive tool, not a replacement for medical treatment. Some small clinical trials show it reduces pain intensity and nausea. Larger Cochrane-level reviews remain cautious — the evidence is promising but not conclusive. That's worth knowing upfront, because the wellness industry is not known for honest nuance on this topic.
Here's what's actually known, and how to do it properly if you want to try it.
The Three Main Points for Migraines
Location
On the back of the hand, in the fleshy webbing between the thumb and index finger. To find the precise spot: press the thumb and index finger together and look for the small muscle mound that rises. Relax the hand, and LI4 sits at approximately the peak of that mound, slightly toward the index finger's metacarpal bone. Another way to locate it: trace along the metacarpal bone of your index finger toward the thumb — LI4 is about two-thirds of the way from the knuckle toward the wrist, on the thumb side of that bone.
How to apply pressure
Use the opposite hand's thumb and index finger, pinching across the webbing. Apply firm, sustained pressure with the thumb on top (back of hand), angling slightly inward toward the bone. You're aiming for a deep, radiating ache — traditional acupuncture refers to this as "de qi," and it's the feeling you want. Surface tingling or pain means you're too shallow or too sharp. Hold for 60–90 seconds. Release slowly. Repeat on the opposite hand. Do 2–3 rounds per side.
What the research shows
LI4 has the most clinical evidence of the three points. A 2011 trial by Melchart and colleagues found that acupressure applied to LI4 (via a wristband device) significantly reduced pain intensity in tension-type headache compared to sham stimulation. A 2018 Iranian RCT (Eghbali et al.) found acupressure at LI4 reduced migraine duration and intensity in a cohort of 56 women — a statistically significant result, though the sample size limits how far you can generalize. LI4 appears repeatedly across headache research as the most consistently supported manual point.
Note: LI4 is traditionally contraindicated during pregnancy and is generally avoided in that context.
Location
At the base of the skull, in the two depressions flanking the spine where the neck meets the occiput. Run your fingers up the back of your neck and feel for the hard ridge of the skull. Immediately below that ridge, on either side of the vertebral prominence, you'll find two distinct hollows — that's where the sternocleidomastoid and trapezius muscles attach to the occipital bone. GB20 sits in those hollows. During a migraine or after prolonged screen time, these spots are often noticeably tender before you even press — that tenderness is diagnostic.
How to apply pressure
Interlace your fingers behind your head and position both thumbs pointing upward into the GB20 hollows. Apply sustained upward pressure at roughly 45 degrees — you're pressing into the skull, not straight back into the neck tissue. Hold for 60 seconds, breathing slowly. Release and repeat two or three times. Alternatively, lie on your back and place a small firm ball (a lacrosse ball, or an acupressure ball) under the base of your skull and let gravity provide sustained pressure for 3–5 minutes. This is particularly effective for migraines with significant neck tension or those that radiate from the back of the head forward.
What it addresses
GB20 is especially relevant for migraines that start at the back of the head, occipital-type pain, and headaches accompanied by neck stiffness. It shows up in headache literature across multiple traditional medical systems — Chinese, Japanese, Korean, and some Tibetan traditions all describe this same anatomical location for head pain, which is notable. The suboccipital muscles here are strongly implicated in referred head pain and tension-migraine overlap.
Location
On the inner (palmar) surface of the wrist, approximately three finger-widths above the wrist crease, between the two central tendons that run down the forearm. To find it: face your palm upward, place three fingers across the wrist starting from the lowest crease, and mark the spot just past those three fingers — between the palmaris longus and flexor carpi radialis tendons. If you flex your wrist slightly, those tendons pop out and the point sits between them. This is the same point targeted by anti-nausea acupressure wristbands (sold as Sea-Bands or similar).
How to apply pressure
Use the opposite thumb to press directly down between the tendons. The pressure should be moderate and sustained — not so hard you're pressing bone, but enough to feel the deep ache. Hold for 30–60 seconds, breathing slowly. PC6 is particularly effective when the migraine comes with nausea, which is a common associated symptom. The wristband approach (where you wear a band with a small bead pressing the point continuously) has been studied specifically for this application.
What the research shows
PC6 has the strongest evidence for nausea specifically — this is where acupressure's clinical record is most solid. A 2015 Cochrane review of acupressure for nausea and vomiting (including migraine-related nausea) found modest but statistically significant benefit. For the head pain component of migraines, the evidence is thinner; PC6 is more a nausea point than a pain point in the research literature. That said, if nausea is part of your migraine pattern, it's worth including.
What the Research Actually Shows
Let's be direct about the evidence landscape. Most acupressure studies for migraine are small — sample sizes of 40–100 people, conducted in single centers, often without adequate blinding (hard to blind someone to whether they're receiving real pressure). The 2022 Frontiers in Neurology network meta-analysis of acupuncture-related therapies covered 39 RCTs and 4,379 patients, finding that acupuncture-related approaches outperformed sham controls for migraine frequency reduction — but acupressure is a subset of that literature, and the effect sizes are modest.
Where acupressure seems to perform best: reducing migraine frequency and associated nausea with regular practice, rather than aborting an active attack. A 2019 randomized trial (PubMed ID 30600173) found self-administered acupressure improved sleep quality and reduced fatigue in migraine patients — two factors that often drive attack frequency. This indirect path may be part of the mechanism.
What the evidence does not support: acupressure as a reliable substitute for pharmacological treatment during an active migraine attack. If you're in the middle of a severe migraine and your triptans are working, acupressure is a complement, not a replacement.
Strongest evidence: PC6 for nausea (Cochrane review, 2015). LI4 for tension headache pain intensity (Melchart et al., 2011).
Moderate evidence: LI4 and acupressure combinations for reducing migraine duration and intensity (Eghbali et al., 2018, n=56).
Honest limitation: No large RCT (500+ participants) has been conducted on acupressure specifically for migraine. Most studies carry moderate risk of bias. The Cochrane Collaboration rates the overall evidence as insufficient to make strong recommendations.
Self-Application During an Attack
During an active migraine, apply pressure in a quiet, dark environment — exactly where you'd want to be anyway. Here's the sequence:
- Lie or sit comfortably with your neck supported. Attempting acupressure while upright and tense will reduce effectiveness.
- Start with GB20 if the pain is at the back of your head or neck — this is often the highest-yield point during an attack. Use the interlaced-fingers thumb technique or the ball method. 60–90 seconds, slow breathing.
- Move to LI4 on both hands — 60–90 seconds each side, 2 rounds. Expect tenderness. That's normal and worth pushing through gently.
- Add PC6 if nausea is present — sustained thumb pressure for 30–60 seconds, or a wristband for ongoing stimulation.
- Pressure level: Firm enough to produce a deep ache but not sharp pain. The traditional target sensation is a dull, radiating heaviness. If you're getting shooting or stabbing sensation, reposition.
- Duration: A full sequence takes 8–12 minutes. You can repeat once after 20–30 minutes if symptoms haven't improved.
Realistic expectation: you may get some reduction in pain intensity or nausea. You probably won't abort the migraine entirely, especially if it's already in full swing. The earlier you apply pressure (at the prodrome or aura stage, before pain peaks), the better the odds of meaningful relief.
Prevention vs. Acute Treatment
This distinction matters. The evidence is actually somewhat better for acupressure as a preventive tool used regularly than for acute in-attack use.
The theory: regular stimulation of these points over weeks and months may reduce central sensitization — the process by which the nervous system becomes progressively more reactive to migraine triggers. Chronic migraine involves measurable changes in how the trigeminal nerve and brainstem process pain signals. Sustained, regular manual therapy may dampen that sensitization over time, similar to how some other non-pharmacological approaches (biofeedback, mindfulness, exercise) reduce migraine frequency without working through the acute pain pathway.
Acupressure mats and prevention: Lying on a spike mat (also called acupressure or Shakti mats) for 15–20 minutes daily may contribute to migraine frequency reduction through two mechanisms: (1) sustained diffuse pressure triggers endorphin and oxytocin release, and (2) the mat promotes the kind of deep muscle relaxation and stillness that reduces cortisol levels — a known migraine trigger. The evidence is largely indirect here, drawing from the acupressure literature and mat-specific research on pain and stress, but the mechanistic rationale is sound.
In Canada, acupressure mats are available at well.ca and Chapters/Indigo. They vary in spike density and cushioning — softer mats are easier to start with, denser spikes provide stronger stimulation.
When Not to Use Acupressure
Neurological symptoms: If your headache is accompanied by vision changes (sudden visual loss, double vision, new visual aura in someone who doesn't normally have aura), weakness or numbness on one side of the body, confusion, difficulty speaking, or the worst headache of your life that came on suddenly — stop everything and get to an emergency room. These are red flags for conditions like subarachnoid hemorrhage, stroke, or intracranial mass. Acupressure is not appropriate and you need immediate medical evaluation.
Medication-overuse headache (MOH): If you're using pain medication — including over-the-counter drugs like ibuprofen, acetaminophen, or naproxen — more than 10–15 days per month, and you're getting daily or near-daily headaches, you may have medication-overuse headache. Manual therapies including acupressure can temporarily relieve MOH symptoms, but this temporary relief may reinforce the cycle and delay proper treatment. MOH requires gradual medication tapering under medical supervision, not pressure point therapy.
New or changed headache pattern: Acupressure is appropriate for your established migraine pattern that has been previously evaluated. A new or significantly changed headache — different location, different character, different onset — should be assessed by a physician before you treat it with any home approach.
Canadian Context
If you want to explore regular acupressure for migraine prevention, a few practical notes:
- Acupressure mats: Available at well.ca (often $30–$70 CAD range), Chapters/Indigo, and many Canadian pharmacies. Look for mats that include a neck pillow — the neck piece is particularly relevant for GB20-area stimulation.
- Acupressure wristbands for PC6: Sea-Bands and similar products are sold at most Canadian drugstores (Shoppers Drug Mart, Rexall, London Drugs) in the travel section. They're also effective for nausea during migraines and cost under $15 CAD.
- Professional support: Registered acupuncturists (R.Ac.) in Canada can provide formal acupressure and acupuncture treatment. Many provincial benefit plans cover a portion of acupuncture costs. If self-application isn't providing adequate relief, this is a reasonable next step.
- Migraines Canada (migrainecanada.org) maintains an up-to-date resource on all migraine treatment approaches and is worth bookmarking as a primary reference.
