Cupping therapy works by creating a vacuum seal against the skin, drawing up underlying tissue to increase local circulation, release myofascial tension, and stimulate the nervous system's pain-regulation pathways. As a traditional Chinese medicine technique I've used for over twenty years in Cambridge and Saffron Walden, cupping delivers results that surprise patients who expect little more than a massage — particularly for stubborn muscular pain, respiratory conditions, and stress-related tension that doesn't respond well to needles alone.
What Happens to Your Body During Cupping?
When a cup is placed on the skin and the air is evacuated — either by heating the cup traditionally or using a modern suction pump — the vacuum pulls the skin, fascia, and superficial musculature upward by several centimetres. This "negative pressure" produces a cascade of physiological effects that distinguish cupping from all forms of compression-based massage.
The most precise mechanism identified in recent research involves nitric oxide: the vacuum-induced mechanical stress on capillary endothelial cells triggers a localised release of nitric oxide, a signalling molecule that causes smooth muscle in blood vessel walls to relax, producing a rapid and sustained increase in local vasodilation. This is more specific than the generic "increases blood circulation" explanation in most cupping articles — it explains why the effects persist for several hours after the cups are removed, not just during treatment.
Simultaneously, the sustained lift of myofascial tissue creates a mechanical separation of adherent fascial layers, reducing the neuromuscular hypertonicity that maintains tension in chronically shortened muscles. This is the mechanism behind cupping's effectiveness for the kind of deep muscular tightness — shoulders, upper back, hip flexors — that Swedish massage releases only temporarily. For how these effects interact with needling, see our page on acupuncture treatment.
What Conditions Can Cupping Help With?
In my Cambridge practice, I most commonly use cupping for:
- Musculoskeletal pain: Chronic upper back and shoulder tension, lower back pain, neck stiffness. Cupping is particularly effective for dense, rope-like trigger points that don't release with superficial work. A 2018 Journal of Traditional Chinese Medicine systematic review of 16 RCTs found cupping significantly reduced pain intensity compared to no treatment for musculoskeletal pain.
- Sports recovery: The technique became globally visible after the 2016 Olympics (Michael Phelps's circular marks). Sports medicine clinicians use it to accelerate lactic acid clearance and reduce delayed onset muscle soreness (DOMS) after high-intensity training.
- Respiratory conditions: Classical Chinese medicine uses cupping on the upper back (Bladder and Lung channel points) for acute respiratory illness — specifically to "release the exterior." Modern use includes post-viral fatigue and bronchitis recovery.
- Stress and nervous system regulation: For patients whose tension is stress-driven and systemic, cupping's parasympathetic activation effect works alongside acupuncture to downregulate the nervous system. See our page on musculoskeletal pain conditions for the full scope of presentations I treat with combined cupping and acupuncture.
Dry Cupping vs. Wet Cupping: An Important Distinction
Most cupping practised in the UK — including in my Cambridge practice — is dry cupping: no skin incision, no blood drawn. The cups are applied by suction and removed cleanly. Evidence for dry cupping's musculoskeletal and pain effects comes from a substantial body of clinical trials conducted primarily in China, Korea, Germany, and the UK.
Wet cupping (known as hijama in Islamic medical tradition) involves creating small skin incisions before applying the cups to draw a small amount of blood. It has a separate evidence base, is practised by a distinct group of regulated practitioners, and has different indications and contraindications from dry cupping. When you read general "cupping research," it is important to clarify which form the studies examined — conflating the two produces misleading conclusions about both treatments.
What Do the Cupping Marks Mean?
The circular discolouration cupping leaves — from pale pink to deep purple-red — often concerns patients who mistake them for bruises. They are not bruises in the conventional sense. Bruising results from traumatic capillary rupture under compressive force; cupping marks are produced by suction drawing stagnant interstitial fluid and extravasated red blood cells to the surface from deeper tissue layers.
The colour and intensity of the marks are diagnostically meaningful in Chinese medicine. A pale mark suggests good local circulation. A deep purple-red mark in a patient with chronic shoulder tension indicates significant stagnation — exactly what the treatment is addressing. As circulation improves across a course of treatment, the marks typically become lighter and resolve more quickly, which is a positive sign of improving tissue health.
Marks typically fade within 3–7 days. Patients should be aware before social or formal events, and should inform their practitioner of any bleeding disorder or anticoagulant medication, which are contraindications.
What to Expect in a Cupping Session
I offer cupping therapy at Amanda Ody's practice as a standalone treatment or integrated into an acupuncture session, depending on what your presentation requires. If we're treating musculoskeletal pain, cupping typically follows the acupuncture needles — the needles work on the channel system while the cups address the structural tissue layer above.
Cups are usually retained for 8–15 minutes. The sensation is distinctive: an initial pulling pressure, then a warm heaviness as circulation increases. Most patients find it deeply relaxing — the parasympathetic effect often produces the same deeply rested state as a full massage, but with more targeted tissue change. I use silicone cups for most applications, which allow me to perform "sliding cupping" over oiled skin — combining the fascial separation of stationary cupping with the coverage of massage.
Frequently Asked Questions About Cupping Therapy
What does cupping therapy do to your body?
Cupping creates a vacuum seal against the skin, drawing up the skin, underlying fascia, and superficial musculature. The negative pressure triggers nitric oxide release from capillary endothelial cells, producing localised vasodilation that increases circulation to the treated area for several hours post-treatment. Simultaneously, the sustained lift of myofascial tissue creates a mechanical separation of adherent fascial layers, releasing the tension that causes deep knots and restricted movement. The nervous system response — the parasympathetic activation associated with the warm, heavy sensation of retained cups — also modulates pain perception and stress hormones systemically. The combined effect is increased local circulation, reduced myofascial tension, and whole-body relaxation.
How long do cupping marks last, and are they bruises?
Cupping marks typically resolve in 3–7 days, sometimes a little longer in patients with poor circulation or significant stagnation. They are not bruises in the conventional sense: bruising results from traumatic capillary rupture under compressive force, while cupping marks are caused by suction drawing stagnant interstitial fluid and extravasated cells to the surface from deeper tissue. In Chinese medicine, the colour is diagnostically meaningful — deep purple-red marks indicate significant stagnation; pale pink marks suggest already good circulation. As you respond to treatment over multiple sessions, the marks typically become lighter and resolve faster — a positive sign of improving tissue health.
Is cupping therapy painful?
Most patients find cupping deeply comfortable — often more so than deep tissue massage, which is compressive. The sensation during treatment is a pulling pressure and warmth as circulation increases. Stationary cupping (cups left in place for 8–15 minutes) is generally well-tolerated; sliding cupping over oiled skin is described by most patients as similar to a firm, flowing massage. The area may feel tender to the touch for a day or two after treatment, similar to post-exercise soreness — this is a normal tissue response. Contraindications include active skin lesions or inflammation in the treatment area, pregnancy (certain points), and anticoagulant medication — always inform your practitioner.
What conditions can cupping help with?
Cupping is most clinically evidenced for musculoskeletal pain — chronic back, shoulder, and neck tension; sports recovery; and trigger point release. Clinical research (including a 2018 systematic review of 16 RCTs) supports its use for pain intensity reduction compared to no treatment. In traditional Chinese medicine practice, it is also used for respiratory conditions (bronchitis, post-viral fatigue, acute illness), digestive complaints (abdominal cupping for bloating), and stress and nervous system regulation. I use it clinically in combination with acupuncture for the conditions listed on our musculoskeletal pain page — most often back pain, neck and shoulder tension, and sports injuries.
How many cupping sessions do I need?
For acute musculoskeletal tension — a stiff neck after poor posture or a short-term shoulder injury — two to four sessions over two to three weeks is typically sufficient. For chronic conditions, particularly longstanding back tension or post-viral fatigue where tissue stagnation has accumulated over years, six to eight sessions provides a more meaningful course. I typically incorporate cupping into acupuncture sessions rather than offering it as a standalone treatment, which means frequency follows acupuncture scheduling: weekly initially, then fortnightly as improvement consolidates. Maintenance cupping every four to six weeks is beneficial for patients with physically demanding work or chronic postural tension from desk-based roles.
Can I have cupping alongside acupuncture?
Yes — in Chinese medicine, cupping and acupuncture are complementary tools that work at different tissue levels. Acupuncture works through the channel system (nervous system, connective tissue planes, energetic pathways); cupping works primarily on the fascial and vascular layers directly under the skin. In a single session treating shoulder tension, for example, I might needle distal points on the arm and leg to clear the channel pattern while using cups on the upper back to release the structural tissue simultaneously. This layered approach frequently produces faster and more durable results than either technique alone. Most of my acupuncture patients experience cupping in at least some of their sessions.
