Acupuncture, decoded.
What acupuncture is, how it works in your body, and what the evidence really shows, with real sources. Then, where to find someone good in San Diego.
A 2,500-year-old practice, taken seriously by modern science.
Acupuncture is the practice of placing very fine, single-use needles at specific points on the body to prompt a response from the nervous system. The evidence is strongest for chronic pain, migraine and tension headache, and thinner elsewhere. This page says which is which, and shows the sources.

What it actually is
Acupuncture places hair-thin, single-use needles at specific points on your body. Nothing like the needle for a shot.
A first visit starts with a few questions, then the needles go in and you rest for up to half an hour. Most people come weekly for a stretch. It’s a 2,500-year-old practice that modern science is still catching up to.

The mechanism
What's actually happening
Not magic, not just tradition. Here’s the modern science, in plain terms.
It talks to your nervous system
The needles stimulate your central nervous system, which responds by releasing your body's own chemistry.
Your body makes the medicine
That response includes endorphins, your natural painkillers, plus neurotransmitters that help regulate how you feel.
It changes pain signaling
Brain-imaging shows real effects on nervous-system activity, and the tissue around each needle responds too.

How it fits with regular medicine
This isn’t medicine versus acupuncture. The best way to think about it is two different jobs that work well together.
Conventional care
Usually targets a specific diagnosis with a specific tool: a drug, a procedure, a test. Precise and powerful for what it’s built for.
Acupuncture
Comes from a whole-body tradition and nudges your own systems to respond. Today it’s used as integrative care, alongside your regular team, not instead of it. Cleveland Clinic
The receipts
What the evidence actually shows
The strongest evidence is for managing and preventing flare-ups of conditions people already live with.
Chronic pain
Across 39 trials, it eased ongoing pain more than both no treatment and placebo needling. Its edge over placebo needling is relatively modest.
Migraine prevention
Added to usual care, it at least halved migraine frequency for 41 of 100 people, versus 17 of 100 on usual care alone. It may work about as well as some older preventive medicines, with fewer side effects.
Tension headaches
For frequent or chronic tension headaches, adding it to usual care about doubled how many people had their headache days cut in half. The edge over sham needling was smaller.
Low back pain
A major U.S. physician guideline lists acupuncture among the first non-drug options to try for chronic low back pain, before medication.
Nausea & vomiting
Stimulating one wrist point (PC6) can reduce post-surgery nausea. It works best alongside standard anti-nausea medicine, not instead of it.
Knee osteoarthritis
In some high-quality trials, the benefit held for up to a year after treatment ended.
The wider toolkit
What else your acupuncturist may offer
Most acupuncturists work with more than needles. These six come up most often, picked to suit what you came in for.

Cupping
Gentle suction that gets blood moving.
Warmed cups create gentle suction that pulls fresh blood into tight, achy spots. People use it to ease sore muscles, neck, back, and shoulders, and the session itself tends to feel relaxing. Early evidence supports its use for muscle tension, with more research still building.
Meta-analysis, 72 RCTs
Moxibustion
Warming specific points with burning mugwort.
Dried mugwort is warmed just above the skin to send gentle, focused heat into a single point. Its best-studied use is a surprising one: added to usual care, it may help turn breech-position babies late in pregnancy. Otherwise it’s a traditional warming therapy for digestion and low energy.
Cochrane, 2023
Gua sha
A smooth tool stroked along the skin.
A smooth-edged tool is stroked firmly along the skin to lift circulation and release muscle tension, most studied for a tight neck and shoulders, with early evidence that looks promising. The gentle facial version is a different, lighter technique, a lovely ritual many enjoy for a fresh, temporary glow, with more research still to come on lasting results.
Cleveland Clinic
Tui na (acupressure)
Chinese therapeutic massage.
Hands-on Chinese massage that works your muscles and circulation like skilled bodywork, applied along traditional lines. People use it to loosen a stiff neck or back and to unwind, and some sleep better after. It works through the same physiology as good massage, and early studies point in a positive direction, with more research to build on.
Meta-analysis, 5 RCTs
Natural herbal medicine
Personalized herbal formulas.
A practitioner matches a personalized formula to you, the most prescription-like of these practices. In the US these are sold as dietary supplements rather than FDA-approved drugs, and research is still growing. Worth exploring with a practitioner, and a quick word with your doctor, especially if you take other medications.
NCCIH (NIH)
Infrared treatment
Deep, radiant heat over a sore area.
A far-infrared lamp (the reddish heat lamp in many clinics, often called a TDP lamp) warms the tissue directly, widening local blood vessels and lifting blood flow to the area. That can relax tight muscles and ease stiffness, and early studies suggest it may help ease pain in spots like an arthritic knee. It’s a comfortable, low-risk addition to your care, with more research still building.
Systematic review, PMCThe bigger idea
The point isn’t stopping one bad day. It’s having fewer of them.
Most people try acupuncture during a flare. But the strongest research points somewhere better: prevention. In the migraine studies, the real win wasn’t ending one attack, it was having fewer of them. Cochrane, 2016
That’s the whole KeepCare idea: care that keeps you ahead of a recurring problem, not just chasing it after it hits.
Real talk
Stuff people actually ask
So, does it actually work?
For some things the research is solid and consistent (see the numbers above), for others it's early or thin. We only make a specific claim where we can point to the research, and we tell you how solid it is.
Is it safe?
With a trained pro and sterile, single-use needles, serious problems are rare, usually just mild soreness or a small bruise. Most reported issues trace back to untrained hands, which is why who you see matters.
Does it hurt?
The needles are about as thin as a hair, nothing like a shot. Most people feel a tiny pinch at most, then usually settle in and relax while they're in.
How much does acupuncture cost?
It varies by practice. First visits are longer and usually cost more than follow-ups, and many practices price a course below the single-visit rate. Every practice lists its own pricing on its page.
