Cupping in physiotherapy is a soft tissue technique in which a practitioner places cups on the skin and creates vacuum suction, lifting the skin and underlying fascia upward instead of pressing down into it. That upward direction is the whole difference between cupping and most hands-on treatment, and it is why cupping is used for tight, restricted tissue that has not responded to direct pressure. Below we cover what cupping actually does, what the research shows and how strong that evidence is, how a session is performed, what the marks mean, what to do afterward, who should avoid it, and how it compares to massage.

What Is Cupping in Physiotherapy?

Cupping in physiotherapy is the application of suction cups to the skin to influence myofascial tissue, lifting the skin and fascia upward rather than compressing them downward. Downward compression is what a thumb, elbow, or forearm delivers during most manual therapy. Cupping reverses that direction, which changes what happens to the layers underneath.

Underneath the skin sit layers of fascia and muscle that normally glide against each other, and practitioners today use plastic, silicone, or glass cups with a vacuum seal to influence the physiology of that myofascial tissue, according to the College of Physiotherapists of Ontario. Ontario’s regulator also notes that the technique is old: cupping stretches back thousands of years, with cattle horns, bronze cups, and bamboo all used at various points across different regions and eras.

Different eras used different materials for the same basic mechanism, and the mechanism is where the modern rationale sits.

What Does Cupping Do?

Cupping decompresses the soft tissue layers beneath the cup, creates space between muscle and fascia, and draws additional blood flow to the treated area. Blood flow to a local area brings oxygen and nutrients toward tissue that is healing, and the decompression is intended to reduce the restriction that limits how freely those layers slide against each other.

Sliding freely matters because restricted fascia limits movement even when the muscle itself is healthy. Healthy muscle under restricted fascia still feels tight, which is the presentation cupping is most often selected for. Selection happens alongside other tools rather than instead of them, and it works the same way K-Laser therapy does: as something that makes the active part of your treatment easier to progress.

Does Cupping Pull Out Knots?

No, cupping does not pull anything out of your body, and it does not physically remove knots. Knots, more accurately described as areas of increased muscle tone and tenderness, are not objects that can be extracted. Extraction is a common way people describe how cupping feels, and it is worth being clear about what is actually happening: the suction lifts and separates tissue layers, which reduces the restriction and tenderness in that area. Tenderness reducing is a real effect. Material being drawn out of the body is not, and any practitioner describing cupping in those terms is describing something that does not occur.

What Conditions Is Cupping Used For?

Cupping is used most often for tight or restricted soft tissue, low back pain, neck and upper back tension, shoulder tightness, and muscle soreness related to training or repetitive work. Repetitive work and training both produce the kind of diffuse, layered tightness that responds to broad-area techniques. Broad-area treatment is also why cupping is frequently applied to the back, where there is enough muscle bulk and flat surface for the cups to seal properly.

Is Cupping Good for Muscles, and What Does the Evidence Show?

Cupping has moderate evidence for improving soft tissue flexibility, low to moderate evidence for reducing low back and neck pain, and very low to low evidence for other musculoskeletal conditions, according to a systematic evidence-based review of cupping in musculoskeletal and sports rehabilitation. That same review found the incidence of adverse events across the studies to be very low, which is the other half of an honest answer: modest benefit, low risk.

Low risk and modest benefit is a reasonable profile for an adjunct technique, and it is not a reasonable profile for a standalone treatment plan. Standalone use is where cupping gets overclaimed. We use it as one component alongside manual therapy and loading, because exercise rehabilitation is what produces durable change in tissue capacity, and cupping is one of the things that can make progressing that loading more comfortable.

Outcome	Evidence level	What that means in practice
Increasing soft tissue flexibility	Moderate	The strongest supported use. Reasonable to expect improved tissue mobility in the treated area.
Decreasing low back pain	Low to moderate	Worth trying as part of a broader plan. Not a substitute for loading and movement retraining.
Decreasing cervical (neck) pain	Low to moderate	Same as above. Often paired with manual therapy and postural work.
Other musculoskeletal conditions	Very low to low	Evidence is thin. Should not be the primary treatment for these presentations.
Adverse events	Very low incidence	Generally well tolerated when performed by a qualified practitioner on suitable candidates.

Comparators across the reviewed studies included non-intervention, standard medical care, heat, routine physiotherapy, electrical stimulation, active range of motion and stretching, passive stretching, and acetaminophen.

Comparators of that kind matter when reading any claim about cupping, because a technique that outperforms doing nothing has not necessarily outperformed the exercise programme you would otherwise be doing. Otherwise-available treatment is the honest benchmark, and Ontario’s Evidence-Informed Practice Standard, in effect since November 1, 2024, requires physiotherapists not to promote treatment options that are not grounded in scientific and physiologically plausible evidence.

How Is Cupping Performed?

Cupping is performed by placing cups on the skin and generating suction, either by compressing the cup manually, using a mechanical pump, or applying heat. Heat, manual compression, and pump-generated suction all produce the same negative pressure inside the cup, and the choice depends on the equipment and the technique being used.

Two techniques are permitted in physiotherapy practice in Ontario:

• Dry cupping. Cups are applied to the skin using suction and left stationary. Research recommends a maximum of five to ten minutes per session, which is long enough to achieve the intended effect without unnecessary discomfort or reaction.
• Oil or sliding cupping. Oil or lotion is applied to the skin first, then the suctioned cup is glided along the tissue, covering a wider area and acting more like a deep tissue technique across larger muscle groups.

Larger muscle groups suit the sliding technique and smaller focal areas suit stationary cups, so a session may use both. Both are selected during treatment rather than booked in advance, because the technique follows the assessment. Assessment-led selection is how every soft tissue technique is chosen here, including the ones covered in the guide to types of physiotherapy.

Can Physiotherapists Do Cupping in Ontario?

Yes, physiotherapists in Ontario can perform cupping, but only dry cupping and oil cupping, according to the College of Physiotherapists of Ontario. The College states that techniques involving bloodletting or the use of a scalpel to pierce the skin, including wet cupping or Hijama, are outside the physiotherapy scope of practice and should not be performed.

Performed treatment must also address the physiotherapy diagnosis and treatment goals set for that patient, safely and competently, rather than being applied because a patient requested it. Requesting a specific technique is fine, and whether it fits your presentation is a clinical decision. Clinical decisions about your musculoskeletal problem are made during physiotherapy assessment, and where cupping is indicated it is one option among several.

Who Is Qualified to Perform Cupping?

Cupping may be performed by physiotherapists, registered massage therapists, chiropractors, and acupuncturists, each governed by their own regulatory college with its own scope rules. Scope rules differ between those colleges, which is why the same technique can be permitted with different limits depending on who is delivering it and why they are delivering it.

Delivering cupping at our clinic falls to our registered massage therapists. Cindy-Coco Qiao Zhu Huang, RMT, a graduate of Oxford College registered with the College of Massage Therapists of Ontario, is trained in cupping alongside deep tissue massage, soft tissue mobilization, trigger point therapy, hot stone, and prenatal techniques. Shuxian (Maggie) Wang, RMT, an Advanced Diploma graduate of Protégé School, offers cupping alongside myofascial release, gua sha, deep tissue massage, and manual lymphatic drainage. If cupping is what your tissue needs, registered massage therapy is where you will find it here, and medical acupuncture is available separately for presentations where needling is the better fit.

Does Cupping Hurt, and What Does It Feel Like?

Cupping does not usually hurt, and most people describe it as a firm pulling or tugging sensation rather than pain. Pain is not the goal and it is not a marker of effectiveness. Effectiveness has nothing to do with how intense the suction feels, and a session that leaves you wincing has been dosed too aggressively.

Aggressive dosing is avoidable because suction is adjustable. Adjustable pressure means you should speak up during the session if the pull becomes uncomfortable, exactly as you would about pressure during a massage. With sliding cupping the sensation changes to a deep, dragging stroke, and with stationary cups you feel a steady localized pull for the five to ten minutes the cups remain in place. In place afterward, the treated skin often looks red, which is expected: localized erythema and ecchymosis are the common effects of dry cupping.

What Do Cupping Marks Mean?

Cupping marks are residual ecchymosis from the suction, appearing as circular or oval areas of skin discoloration that range from light red or pink to dark purple depending on your skin type and the intensity of the treatment. Treatment intensity and individual skin type are the two variables that determine mark colour, according to research published through the National Center for Biotechnology Information.

Colour is the most misunderstood part of cupping, so it is worth being precise about what the marks do and do not indicate.

1. They are a normal, expected result of suction. Marks appear because negative pressure draws blood toward the surface within the treated circle.
2. They are not a measure of how much dysfunction you have. A darker mark does not mean tighter tissue or a worse problem.
3. They are not an indicator of anything being removed from the body. Nothing is drawn out of you during dry or oil cupping.
4. They are not a sign the treatment worked. Improvement is measured by how you move and how you feel, not by mark colour.
5. They are not a wound. The skin is unbroken in dry and oil cupping, which is precisely why those are the techniques permitted in regulated practice here.

How Long Do Cupping Marks Last?

Cupping marks typically fade and disappear within one to ten days after treatment. Ten days is the outer end of that range and applies mainly to darker marks from more intense sessions, while light pink marking often clears within a couple of days. A couple of days is the usual experience for a first session, since practitioners generally start conservatively.

Is a Cupping Mark the Same as a Bruise?

A cupping mark is a form of bruising, since both involve blood pooling under intact skin, but the mechanism differs: a bruise comes from impact trauma and a cupping mark comes from sustained negative pressure. Negative pressure produces the distinctive round, evenly bordered shape that impact rarely creates. Creating that regular circular pattern is also why cupping marks can be mistaken for injuries by people who do not recognize them, a point clinicians are specifically advised to be aware of, so it is worth mentioning your treatment if anyone asks.

What Should You Do After Cupping?

After cupping you should drink water normally, keep moving gently, protect the treated skin, and avoid stacking intense demands onto the area for the rest of the day. The rest of the day is the window when tissue is most sensitive, and the sensible list is short: skip heavy training on the treated area, skip very hot showers, saunas, and hot tubs for several hours, keep the marks covered if they will be exposed to strong sun, and avoid vigorous rubbing or additional deep pressure on the same spot.

The same spot feeling tender or slightly achy for a day is normal, similar to how muscles feel after deep tissue work. Deep tissue soreness of that kind settles within twenty four to forty eight hours. Forty eight hours is the threshold worth watching: soreness that is escalating rather than fading, skin that blisters, or pain that is sharp rather than achy should be reported to your therapist, because it means the dose was too high and the next session needs adjusting. Adjusting the plan is straightforward, and our massage therapists at our clinic in Markham will change technique, pressure, or dwell time based on how you responded to the previous session, alongside the aftercare advice and stretches they send you home with.

How Often Should You Get Cupping?

Cupping is generally spaced so the previous marks have faded before the same area is treated again, which for most people means about once a week during an active problem. An active problem may warrant weekly sessions for the first few weeks, spacing out as symptoms improve, and maintenance intervals of three to six weeks work for many people afterward. Afterward-scheduling depends on your condition and goals, and treating the same area repeatedly before it has recovered offers no added benefit.

Who Should Avoid Cupping?

Cupping should be avoided or approached with medical clearance if you have a bleeding disorder, take blood-thinning medication, have fragile or compromised skin, have a skin infection, open wound, recent scar, or active inflammatory skin condition in the area, have deep vein thrombosis or a history of blood clots, or are undergoing treatment that affects your skin integrity or immune function. Immune function and skin integrity both matter because suction stresses the tissue at the surface, and cups also need intact healthy skin to seal safely.

Safe sealing rules out certain areas regardless of health status: cups are not applied over bony prominences with little tissue underneath, over the front of the neck and throat, over the face in standard therapeutic cupping, over varicose veins, or directly over a recent injury or fracture site. Fracture sites and other high-risk areas are identified during the assessment rather than at the point of treatment, which is why a physiotherapy assessment or a massage therapy assessment comes first and includes a health history. Health history is also the reason to disclose your medications and conditions before any soft tissue technique, not just cupping.

Is Cupping Better Than a Massage?

Cupping is not better than massage, and the two do different things well enough that they are usually combined rather than compared. Comparing them treats cupping as a substitute when it is really a technique that sits inside a treatment session. Sessions here are built that way: massage therapy in Markham at our clinic begins with an assessment of soft tissues, posture, and movement patterns, and the technique is chosen from there, whether that is deep tissue, trigger point work, myofascial release, cupping, or a combination.

Combinations work because compression and decompression address tissue from opposite directions. Opposite mechanical directions give a therapist more options for stubborn tissue than either alone, and our massage therapists select between them based on how your tissue responds. Responding tissue is also monitored across disciplines here, since our multidisciplinary care model has massage therapists, physiotherapists, and chiropractors sharing notes on the same patient, and chiropractic care often runs in parallel where joint restriction is part of the picture.

Frequently Asked Questions

What Is the Difference Between Dry Cupping and Wet Cupping?

Dry cupping uses suction on intact skin, while wet cupping involves piercing or scarifying the skin and drawing a small amount of blood. Blood-drawing techniques including Hijama are outside the physiotherapy scope of practice in Ontario and should not be performed by physiotherapists, according to the College of Physiotherapists of Ontario. Only dry cupping and oil cupping, where lubricant allows the cup to glide, are within scope.

Is Cupping Covered by Insurance in Ontario?

Cupping is not usually billed as its own service; it is typically included within a registered massage therapy or physiotherapy appointment, which means coverage follows whatever your plan allows for that appointment type. Plan terms vary between insurers, so confirming your specific coverage with your provider before booking is worthwhile. Most extended health plans in Canada include registered massage therapy and physiotherapy when delivered by a licensed practitioner.

Can You Get Cupping While Pregnant?

Cupping during pregnancy requires individual assessment, and it is not automatically ruled out or automatically appropriate. Appropriateness depends on your stage of pregnancy, your health history, and which area needs treatment, with the abdomen and low back generally avoided. Prenatal massage is a well-established option for pregnancy-related back, hip, and postural discomfort, and our RMT Cindy-Coco Qiao Zhu Huang is trained in prenatal techniques, so raising it at the start of your appointment lets your therapist choose what suits you.

How Long Has Cupping Been Used?

Cupping has been used for thousands of years, with its history stretching back to ancient times, according to the College of Physiotherapists of Ontario. Techniques and materials evolved with geography and available resources, and cattle horns, bronze cups, and bamboo were all used before the plastic, silicone, and glass cups practitioners use today.

Do You Need a Referral for Massage Therapy or Physiotherapy in Ontario?

No, you do not need a referral for either massage therapy or physiotherapy in Ontario, because registered massage therapists and physiotherapists are both primary care practitioners who can assess and treat you directly. Some extended health plans require a referral before reimbursing treatment, so it is worth checking your specific policy before your first visit.

The Bottom Line

Cupping is a soft tissue technique that lifts skin and fascia with suction rather than compressing them, and the honest case for it is modest and specific: moderate evidence for improving tissue flexibility, low to moderate evidence for low back and neck pain, and a very low rate of adverse events. Adverse events being rare is what makes it a reasonable technique to include in a plan. What it is not is a treatment that removes anything from your body, and mark colour tells you nothing about how much dysfunction you have.

Dysfunction is identified by assessment, and the right technique follows from that rather than from what you booked.
