Cupping therapy has the strongest evidence for relieving chronic back pain, reducing migraine severity, and supporting muscle recovery after intense exercise. It also shows promise for certain skin conditions, neck pain, and general inflammation. The therapy works by creating suction on the skin, which increases local blood flow, draws immune cells to the area, and stimulates the body’s natural pain-relief pathways. Here’s what the research actually supports.
Chronic Back and Neck Pain
Pain relief is the most well-studied benefit of cupping. A systematic review and meta-analysis found a statistically significant reduction in pain intensity scores for people with chronic back pain who received cupping therapy. The effect appears to come from several mechanisms working together: the suction increases blood volume in the treated area, elevates the rate at which fluid filters through capillaries, and stimulates lymphatic uptake to clear out accumulated waste products. This combination helps flush inflammatory mediators away from tissues that have been chronically irritated.
Neck pain from cervical spondylosis (the wear-and-tear stiffness that builds up over years) is another condition where cupping has been used with supporting evidence. The therapy is typically applied in multiple sessions rather than as a one-time treatment, though there’s no standardized protocol for how many sessions produce the best results.
Migraine and Headache Relief
Cupping appears to meaningfully reduce migraine severity. In a randomized controlled trial of wet cupping for migraines, participants whose pain had been rated as “unbearable” before treatment reported their average pain dropped by about 49% after the first two sessions. Six weeks into treatment, pain severity had decreased by roughly 62%. Separate research found that cupping reduced severe migraine headaches by 66% and cut the number of headache days per month by about 13%.
The pain relief likely involves the release of endogenous opioids, the body’s own natural painkillers. When wet cupping creates small incisions in the skin, it triggers an inflammatory cell response that prompts these compounds to release, acting as both pain relievers and mood enhancers.
Muscle Recovery for Athletes
Athletes are among the most visible users of cupping, and there’s real physiology behind the trend. In a study on handball players, dry cupping performed after high-intensity exercise lowered levels of creatine kinase, a key marker of muscle damage that spikes after hard training. Players who received cupping also showed beneficial changes in heart rate and cardiovascular function during recovery compared to a control group.
A study on Jordanian team athletes found that wet cupping significantly increased white blood cell counts, neutrophils, lymphocytes, red blood cells, and hemoglobin levels when measured four weeks after treatment. Two inflammatory ratios (monocyte-to-lymphocyte and platelet-to-lymphocyte) dropped significantly, suggesting reduced systemic inflammation. The researchers concluded that wet cupping reinforces cellular immunity, generates younger blood cells, and lowers inflammation markers. For athletes, this translates to potentially faster recovery and a stronger immune response during heavy training blocks.
Skin Conditions
The evidence here is less robust but still notable. Clinical reviews have identified cupping as effective for treating cellulitis, and it has been used with varying levels of evidence for acne, urticaria (hives), and neurodermatitis. The proposed mechanism centers on increased blood circulation and the clearance of inflammatory substances from affected tissue. Cupping’s ability to boost nitric oxide production, which controls blood flow and promotes vasodilation, may help deliver immune cells to skin that’s dealing with infection or inflammation.
How Dry and Wet Cupping Differ
Dry cupping uses suction alone. Glass, silicone, or plastic cups are placed on the skin and either heated or mechanically pumped to create a vacuum. This pulls blood toward the surface, warms the tissue, and increases local circulation. The elevated pressure inside the tissue stimulates the lymphatic system to absorb and drain fluid buildup.
Wet cupping adds a bloodletting step. After a brief period of suction, the cups are removed and small superficial incisions are made with a sterile blade. The cups are then reapplied. The fluid that collects contains elevated concentrations of inflammatory mediators and disease-related substances. Wet cupping triggers a more robust immune response than dry cupping because the incisions stimulate inflammatory cell migration and the release of the body’s natural painkillers.
What the Marks Mean and How Long They Last
The circular marks cupping leaves can look alarming, but they’re generally painless and fade within a few days to two weeks depending on their severity. The color tells you something about what’s happening underneath.
- Light pink or red: Good circulation in that area, minimal stagnation. These typically fade within hours to a day.
- Bright red: An active or acute issue like recent muscle strain or inflammation. The body is actively managing stress in that tissue.
- Dark red or purple: Chronic tension or long-term restricted blood flow. These marks suggest deep-seated blockages and can take up to two weeks to fully fade.
- Yellow or greenish: Usually appears as darker marks heal, indicating the body is breaking down and clearing waste products brought to the surface.
- No marks at all: The area has excellent circulation with little stagnation.
Side Effects and Risks
The most common side effect is temporary skin discoloration from the marks themselves. Beyond that, cupping can cause burns (if fire cupping is used carelessly), scarring, and skin infections, particularly with wet cupping if sterile technique isn’t followed. It can also worsen eczema or psoriasis in treated areas. Rare but serious complications have been reported, including bleeding inside the skull after cupping on the scalp and anemia from blood loss after repeated wet cupping sessions.
Who Should Avoid Cupping
Cupping isn’t appropriate for everyone. You should avoid it if you have hemophilia or another blood clotting disorder, cancer, organ failure, cardiovascular disease, or an active infection. People with pacemakers, those taking blood thinners, and anyone who is pregnant should also steer clear. It’s generally not recommended for children under 18 or elderly individuals with fragile skin.
