Acupuncture for headaches and migraines: what the evidence shows.

Acupuncture for headaches is one of the better-studied uses of the needles, and the honest answer to whether it works is yes for prevention, with limits worth knowing before you book. A course of sessions can mean fewer migraine days and fewer tension headaches each month; it is not a way to switch off a headache that is already pounding. Here is what the research shows, how many sessions it takes, what it feels like, and when a headache needs a doctor instead.

Does acupuncture work for headaches and migraines?

For migraine prevention, the main summary of the evidence is a Cochrane review of 22 trials and nearly 5,000 people with episodic migraine. Added to usual care, a course of acupuncture left 41 in 100 people with their headache frequency at least halved, against 17 in 100 on usual care alone. The reviewers put it in everyday terms: someone averaging six migraine days a month would drop to about five with usual care, about four with sham (fake) needling or a preventive drug, and about three and a half with real acupuncture.

Two parts of that deserve a plain reading. Real acupuncture beat sham needling, but only by a small margin, so part of the benefit comes from the overall experience of treatment rather than exact needle placement. And in the trials that compared it with preventive medication, acupuncture did at least as well, with fewer people reporting side effects. The reviewers rated the evidence moderate quality and noted that studies longer than a year are lacking.

For tension headaches (the dull, tight band around the head that builds through a stressful day; clinically, tension-type headache), a second Cochrane review of 12 trials found a similar pattern in people with frequent or chronic episodes. In two large trials, 48 in 100 people receiving acupuncture halved their headache frequency, against 17 in 100 with usual care. Against sham needling the gap was smaller: 52 versus 43 in 100. In four smaller trials comparing it with physical therapy, massage or exercise, acupuncture did not come out ahead.

Acupuncture for headaches is a course, not a rescue. The research showing a benefit is built on a series of sessions, usually six or more, measured in headache days over the following months.

Which headaches is acupuncture good for?

Headache is an umbrella word, and what sits under it changes what acupuncture can do:

• Migraine. The most researched use, aimed to prevent attacks during a stretch when they are frequent. The trials were in episodic migraine, and the goal is fewer attacks, not stopping one already under way.
• Tension headaches. Supported for frequent or chronic episodes. The band-like, end-of-day headache that travels with neck and jaw tension is the pattern we see respond most visibly in clinic.
• Headaches that start in the neck. Clinically called cervicogenic headaches: pain referred up from the joints and muscles of the upper neck, often felt behind one eye. Research on acupuncture alone for this type is thinner, so here the needles are one tool alongside hands-on neck treatment. Our guide to headaches that start in the neck covers how to tell them apart.

What acupuncture is not for: a brand-new kind of headache, a sudden severe one, or one with neurological symptoms. Those are physician-first situations, covered in the last section below.

Why a single session in the middle of a headache usually disappoints

The instinct most people have is to book one appointment on a bad day and see whether the needles stop the pain. That is the version of acupuncture with the least support. The trials measured prevention: how many headache days people had in the weeks and months after a course, not whether one session ended one headache.

The second mismatch is treating the head when the driver sits lower. Tight muscles at the base of the skull and across the upper shoulders refer pain forward over the eye and temple, and a stiff upper neck keeps loading them. Needling those muscles helps, but if neck movement stays restricted, the headache pattern tends to come back.

That is why we fit acupuncture into a chiropractic plan rather than running it in isolation. The Precision Spinal Adjustments and hands-on work at a follow-up address the neck mechanics; the needles target the tight tissue the headache is referring from.

Where do the needles go, and what does it feel like?

Rarely into the spot that hurts, which surprises most people booking a first session. For a headache with a neck component, the points that matter are usually along the base of the skull, the upper trapezius (the muscle running from the neck to the top of the shoulder) and the small muscles either side of the upper neck. Points on the hands and forearms are also commonly used, well away from the head.

The needles are hair-thin, single-use and sterile, and in most of these spots they go in only a few millimeters. Most people feel a brief pinch or nothing at the skin, then a dull heaviness or mild ache at the point rather than the sharp sting of an injection. The needles stay in for about 20 minutes while you lie still. If the needles themselves are the worry, what acupuncture actually feels like walks through it in more detail.

How many acupuncture sessions do you need for headaches?

Plan on a course. Both Cochrane reviews concluded that a course of at least six sessions can be a valuable option, for migraine and for frequent tension headaches. The UK's NICE headache guideline suggests up to 10 sessions over five to eight weeks for chronic tension-type headache, and the same for migraine prevention when the usual preventive medicines have not worked or are not suitable.

A realistic arc: some people notice their neck and shoulders carrying less tension within the first session or two, while the change that matters, fewer headache days per month, usually shows itself over four to six weeks. We track it the plain way. You keep a simple headache count, and the number either moves or it does not; if it is not moving after a fair trial, we will say so and change the plan.

Acupuncture here is $60 per session, about 20 minutes, booked on its own or added to a visit, and it is performed by Dr. Andersen, an acupuncture-qualified chiropractor. It is priced separately from the $60 follow-up, which already includes the adjustment and the hands-on work the visit calls for: Pin & Stretch, Cupping & Scraping, Corrective Exercise Programming and manual spinal decompression. Our acupuncture in Cottleville page covers how to start, and the full picture is on our chiropractic services page.

Is acupuncture safe? Side effects to know about

Side effects are usually minor and short-lived. In a German study of more than 229,000 patients treated by physicians, many of them for headaches, 8.6% reported at least one side effect. By far the most common was a little bleeding or a bruise at a needle site, followed by soreness and, less often, dizziness-type symptoms. Serious problems were very rare.

Some people also feel unusually tired for a few hours afterward, and the occasional person notices a mild headache after a first session that settles within a day. It is not a sign the treatment is doing damage, but mention it at the next visit so the dose can be adjusted. Tell us before treatment if you take blood thinners, have a bleeding disorder, have a pacemaker or are pregnant.

When does a headache need urgent medical care?

Acupuncture is for recurring, familiar headache patterns. Some headaches are a different matter. Get seen urgently, at the ER or by a physician the same day, if a headache:

• comes on suddenly and peaks within minutes, the "worst headache of my life"
• comes with fever and a stiff neck, or keeps worsening with a fever
• arrives with new weakness, numbness, confusion, trouble speaking, vision changes or a change in personality
• follows a recent knock to the head
• is set off by coughing, sneezing, straining or exercise, or changes sharply when you stand up or lie down

A new headache pattern after 50, or a clear change in the headaches you usually get, also deserves a physician's look first. We screen for all of this at the assessment and refer out when the picture does not fit.

If your headaches are the recurring, familiar kind, a useful thing to do today is start counting them. A two-week baseline of headache days turns "I think it helped" into a number we can both see, and it tells us quickly whether a course of acupuncture is earning its place.
