How to choose a massage therapist without getting burned
A star rating is a thin basis for choosing the person who will spend an hour with their hands on your spine. Confirm the credential, loop in your own doctor, and ask a few pointed questions before you lie down on the table.
The short answer
Choosing a massage therapist is mostly a matter of what you ask before you book. 45 states and the District of Columbia require a license or certification, so ask which one yours holds. Then tell your own doctor, and ask about training, cost and pressure before you book 60 minutes with anyone new.

What does a massage license guarantee?
A floor, and the floor moves by state. NCCIH reports that 45 states and the District of Columbia regulate massage therapy; in those places a therapist must hold a license or certification before practicing, and the typical requirement has 2 parts — graduation from an approved program, plus a passing exam score. Several states regulate nothing at all, and there the word therapist on a door carries no guaranteed training behind it.
Demand has outrun that patchwork. In 2022, 10.9 percent of U.S. adults used massage therapy, according to national survey data cited by the National Center for Complementary and Integrative Health (NCCIH) — more than double the 4.8 percent who used it in 2002. Most of those people paid out of pocket. The person who will put pressure on your spine warrants more than a glance at a star average, and how to choose a massage therapist comes down to 3 moves: confirm the credential, loop in your own doctor, and ask a few pointed questions before you lie down.
A voluntary credential sits on top of state licensing. Some therapists certify through the National Certification Board for Therapeutic Massage & Bodywork, which sets 3 requirements: specific educational standards, a background check and a passing exam.
Should you tell your doctor before booking a massage?
Yes, and before rather than after. NCCIH leads its list of 6 things to know with a warning that is easy to skip past: don't use massage therapy to postpone seeing a health care provider about a medical problem. A massage that takes the edge off your back pain for a few days can quietly talk you out of getting something checked that needed checking.
The companion advice points the same direction. If you are unsure whether massage suits you, NCCIH suggests raising it with your health care provider, who may also be able to help you choose a therapist. Mayo Clinic, which treats massage as an integrative therapy, states the rule that comes with that whole category: tell your doctor you are trying massage, and keep up your standard treatment alongside it.
Your doctor also knows things the therapist cannot see: whether you are on a blood thinner, whether that ache in your calf could be a clot, whether your bones can take pressure. One short conversation hands over that context before anyone puts weight on it.
However skilled the therapist is, they are working without your chart unless you hand them the relevant parts of it.
Who should check with a doctor first?
Mayo Clinic names 6 situations: a recent heart attack; a bleeding disorder or blood-thinning medication; a recent blood clot in the leg; newer burns; fractures; or severe osteoporosis. In those cases Mayo says massage may be harmful. It should never be done directly on tumors, and healing wounds or nerve damage mean keeping pressure off the affected areas.
The overall risk still reads low. NCCIH says the risk of harmful effects appears to be low, and that massage therapy appears to have few risks when performed by a trained practitioner. The documented serious harms run to 3 kinds — blood clots, nerve injury and bone fracture — and some of those cases involved vigorous techniques such as deep tissue massage, or patients already at higher risk of injury, such as elderly people.
With cancer patients, NCCIH notes, therapists may need to modify their usual approach, sometimes using less pressure in areas made sensitive by the disease or its treatment. Mayo Clinic makes the same point about cancer care: a therapist working with someone who has cancer has to take special precautions, "so finding a skilled therapist is important."
Should a massage hurt to work?
No. Mayo Clinic is direct: you should not feel significant pain during a massage, though some forms can leave you a bit sore the next day. If the therapist is pushing too hard, the instruction runs one sentence long — ask for lighter pressure — and that is a call to make during the session rather than something to sit through.
The research points the same way. When NCCIH summarized the evidence on massage for fibromyalgia, an area where a 2014 evaluation of 9 studies found the benefit depends on continuing therapy at least 5 weeks, it flagged the review authors' view that the therapist should not cause pain. Some of the clearer benefits show up at the gentle end of the scale: NCCIH notes that a 2010 review found massaging preterm infants with moderate pressure may improve weight gain. Set that beside a safety record in which vigorous deep tissue work turns up in the rare reports of clots and fractures, and more pressure starts to look like more risk without more benefit.
When a therapist asks about pressure, answer honestly in the moment. A good one wants the feedback and adjusts without making you feel like a nuisance.
A therapist who reacts badly to a request for less pressure has told you something useful about the rest of the hour.
What should you ask a massage therapist before the first session?
NCCIH's tips read almost like a script: ask about the therapist's training, experience and credentials, then ask how many treatments your situation might take, what each session costs, and whether your insurance covers any of it. None of that counts as rude — it is the exact set of questions the federal health agency on the subject tells you to ask, and since most people pay out of pocket, the cost question is practical.
One question deserves its own beat: style. Massage therapy covers many techniques, and NCCIH alone names 5. It describes Swedish or classical massage as the most common form in Western countries and the core of most training programs, alongside sports massage, clinical massage aimed at specific goals such as releasing muscle spasms, and the Eastern traditions Shiatsu and Tuina. The right style follows from what you want out of the hour.
Ask us the same questions on the phone before you drive over. We are at 6175 Mission St, Daly City, on the Mission Street corridor near the San Francisco line, open daily from 10 AM to 9 PM, and the number is (415) 916-3282. Every treatment room runs its own Levoit air purifier for dust and pollen, the tables are oversized so your arms rest on the table instead of hanging off it, and linens and towels are fresh for every guest. Most of how to choose a massage therapist comes down to whether the answers arrive plainly. The vetting runs in order:
- Confirm the credential first. Check whether your state regulates massage and that the certificate is current — in an unregulated state, the rest of this list is all you have.
- Ask about training, experience and cost — NCCIH's own script, including how many treatments your situation might take and whether insurance covers any of it.
- Ask: have you worked with my condition? This matters most for anyone with cancer, a recent injury or a fragile health situation, where technique has to be adapted rather than applied off the shelf.
- Ask: will you adjust pressure if I ask? The answer should be an immediate yes.
What does the research say massage therapy can do?
Uneven things, and knowing that protects you from overpaying for a promise. NCCIH says outright that much of the research on massage is preliminary or conflicting, even though a fair amount of it points toward some benefit for pain and other symptoms. For low-back pain, a 2015 review of 25 studies with 3,096 participants found short-term pain improvement, but the studies were low quality and the reviewers said they had "very little confidence" that massage is an effective treatment. The American College of Physicians, in its 2017 guidelines, listed massage as an option for acute and subacute low-back pain, though not for chronic low-back pain.
The same shape shows up elsewhere. For neck and shoulder pain, NCCIH reports benefits that may last only a short time. For osteoarthritis of the knee, a small body of research suggests short-term pain relief. For headaches the studies are few and their results inconsistent — one trial of 83 people found that adding hand massage had no effect on migraine frequency. For cancer patients, a 2016 evaluation of 19 studies found some signal for pain and anxiety, rated very low quality. And a 2016 Agency for Healthcare Research and Quality evaluation of 20 studies found massage helpful for chronic low-back pain while grading the strength of that evidence as low.
Part of what you are paying for is the setting rather than the technique alone. Mayo Clinic notes that in most studies people report improved overall well-being, and points at ordinary factors behind that: a quiet, pleasant room, the structured manipulation of muscle and tissue, and the effect of caring human touch. Mayo reads more positive on stress and mood, citing several studies that found a decrease in stress chemicals such as cortisol, and noting that massage releases endorphins, the body's natural painkillers.
The recurring words in those summaries are worth reading literally: low quality, short term, small, not consistent. For several conditions massage may help you feel better, often temporarily, and the strongest claim most of the evidence supports stays a modest one. Mayo Clinic draws the boundary in a single line — a massage may help you relax, but it can't cure everything that ails you, and done incorrectly it could hurt you.
That last clause explains why this guide exists. Before your next booking, do 3 concrete things: confirm the credential, send your doctor a one-line note that you are trying massage, and write down 2 or 3 of the questions above to ask on the phone. That is how to choose a massage therapist, and it costs about 10 minutes.
| Condition | What studies found | Evidence strength |
|---|---|---|
| Low-back pain | Short-term pain improvement in a 2015 review of 25 studies (3,096 participants); ACP 2017 lists massage for acute and subacute pain only | Reviewers had "very little confidence" |
| Neck & shoulder pain | Benefits reported | May last only a short time |
| Knee osteoarthritis | Short-term pain relief | Small body of research |
| Headaches | Few studies; an 83-person trial found no effect on migraine frequency | Inconsistent results |
| Cancer symptoms | Some signal for pain and anxiety in a 2016 evaluation of 19 studies | Very low quality |
| Fibromyalgia | Among the more promising areas; benefit depends on continuing therapy at least 5 weeks (2014 evaluation of 9 studies) | Modest, time-dependent |
Questions people ask
Do massage therapists need a license?
In 45 states and the District of Columbia, yes — NCCIH reports therapists there must hold a license or certification, typically requiring graduation from an approved program plus a passing exam score. Several states have no state-level regulation, so the vetting falls on you. A voluntary national board certification adds educational standards, a background check and an exam on top of that.
Should I tell my doctor before getting a massage?
Yes, and before rather than after. NCCIH warns against using massage to postpone seeing a health care provider about a medical problem, and Mayo Clinic's rule for integrative therapies is to tell your doctor and keep up your standard treatment. Your doctor also knows risk factors the therapist cannot see, such as blood-thinning medication or clot risk.
Should a massage hurt to work?
No. Mayo Clinic says you should not feel significant pain during a massage, though some forms can leave you a bit sore the next day. If the pressure is too much, ask for lighter pressure during the session. The rare documented harms — blood clots, nerve injury, bone fracture — cluster around vigorous techniques and higher-risk patients.
What should I ask a massage therapist before booking?
NCCIH suggests asking about training, experience and credentials; how many treatments your situation might take; the cost per session; and whether insurance covers any of it. Add 3 more: what style they practice, whether they have worked with your condition, and whether they will adjust pressure on request. A practitioner who gets cagey about any of these is telling you something.
Does the research support massage therapy?
Unevenly. NCCIH calls much of the research preliminary or conflicting, with short-term benefit signals for low-back pain, neck and shoulder pain, and knee osteoarthritis, often from low-quality studies. Mayo Clinic reads more positive on stress, citing lower cortisol and released endorphins. The honest summary: massage may help you feel better, often temporarily.
