Can Cupping Cause Blood Clots?

Cupping therapy is an ancient healing technique that involves placing cups on the skin to create suction. This suction gently pulls the skin upward and is believed to stimulate circulation, ease muscle tension, and promote healing. 

Originating thousands of years ago in China and parts of West Asia, cupping was historically used to treat respiratory illnesses such as bronchitis and pneumonia. Today, many people turn to cupping for relief from back pain, headaches, arthritis, and other chronic conditions.

Like many alternative therapies, cupping can have potential benefits but may also pose risks for patients with certain health conditions. In this blog, we’ll explore what cupping does to the body, whether it can contribute to circulatory problems such as blood clots, and what people with vein concerns should know before trying it.

If you’re concerned about circulatory symptoms, including leg swelling, heaviness, or visible veins, a board-certified vein specialist at Center for Vein Restoration can help you find answers and safe treatment options. Schedule a consultation to discuss your symptoms and create a personalized care plan.

What Is Cupping Therapy?

Cupping is performed by a trained provider such as an acupuncturist, chiropractor, massage therapist, or other licensed healthcare professional. Cups made from materials like glass, metal, silicone, plastic, bamboo, or ceramic are placed on the skin, most commonly on the back, shoulders, or legs.

A vacuum is created inside the cup, either by heating or by a suction device. This vacuum pulls the skin slightly upward and increases blood flow to the area beneath the cup.

Many practitioners believe this increased circulation may help:

• Relieve muscle tension
• Reduce pain and inflammation
• Promote healing in injured tissues
• Improve circulation in localized areas

Cupping is sometimes used for conditions including back pain, migraines, arthritis, asthma, carpal tunnel syndrome, and muscle soreness. Some practitioners also claim it may help with skin conditions, fertility concerns, and digestive issues, though research supporting these uses varies.

Types of Cupping

There are two main forms of cupping therapy.

• Dry cupping: This is the most common form. Cups create suction but don’t break the skin.
• Wet cupping: Also known as “hijama,” this method involves making small, superficial cuts in the skin before applying the cups so that a small amount of blood is drawn out.

Wet cupping involves skin punctures, so it carries a greater risk of infection and should only be performed by trained professionals using sterile techniques. 

How Cupping Affects Blood Flow

One of the most noticeable effects of cupping is the round, dark marks left behind after treatment. These marks occur because suction pulls blood toward the surface of the skin.

According to the Cleveland Clinic, cupping may influence circulation in several ways:

• Increased local blood flow: The suction draws blood to the treated area, which may help deliver oxygen and nutrients to nearby tissues.
• Improved peripheral circulation: Cupping can increase circulation in the skin and tissues close to the surface.
• Stimulation of blood vessels: The mechanical pulling of the skin may stimulate small blood vessels and encourage tissue repair.
• Potential lymphatic movement: Some practitioners believe cupping may stimulate lymphatic flow, helping the body remove waste products and excess fluid.

While these circulation changes are temporary, they’re the main reason cupping is thought to relieve muscle tension and soreness.

Can Cupping Cause Blood Clots?

The good news is that there is currently no strong scientific evidence showing that cupping directly causes blood clots.

However, some theoretical concerns exist, particularly for patients with underlying circulation problems or clotting disorders.

Possible Risks to Consider

• Bruising and broken capillaries: Cupping often causes bruising because small blood vessels under the skin break during suction. While usually harmless, significant bruising may occur in sensitive individuals.
• Localized blood pooling: The suction temporarily draws blood toward the skin’s surface. In theory, this pooling could pose a small risk for people who already have clotting disorders or circulation problems.
• Hematoma formation: In rare cases, larger collections of blood under the skin (hematomas) may form.
• Infection risk (wet cupping): If sterile procedures are not followed, infection may occur. The American Journal of Infection Control cites a meta-analysis of 357 clinical studies that found wet cupping practices were associated with an increased risk of hepatitis C transmission when proper medical sterilization standards are not followed.

Cupping performed by a trained professional is considered relatively safe for most healthy individuals. Still, people with certain conditions should consult a doctor before trying it.

Who Should Avoid Cupping?

Cupping may not be appropriate for those who have:

• Blood clotting disorders
• A history of deep vein thrombosis (DVT)
• Severe varicose veins
• Skin infections or open wounds
• Bleeding disorders or blood-thinning medications

If you have symptoms of vein disease or concerns about circulation, discussing them with a vein specialist before trying cupping is the safest approach.

Supporting Healthy Circulation

Whether or not you choose alternative therapies such as cupping, maintaining healthy circulation is key to protecting your veins.

Healthy habits include:

• Regular physical activity
• Maintaining a healthy weight
• Avoiding prolonged sitting or standing
• Staying hydrated
• Elevating the legs when resting
• Wearing compression stockings if recommended

If symptoms persist, minimally invasive vein treatments can often provide long-lasting relief.

When to See a Vein Specialist

Cupping may offer temporary relief for muscle tension, but it shouldn’t replace medical evaluation for vein symptoms.

If you notice persistent leg pain, swelling, or visible veins, a vein specialist can perform a simple ultrasound exam to determine whether vein disease is present and recommend the best treatment.

The compassionate, board-certified physicians at CVR specialize in diagnosing and treating vein disease through advanced outpatient procedures.

Don’t ignore symptoms that could indicate vein problems! Schedule a consultation with a CVR vein specialist today to learn about safe, effective treatments that can restore your comfort and confidence.

Frequently Asked Questions

Q: Can cupping worsen varicose veins?

A: Cupping placed directly over varicose veins may irritate fragile veins and potentially increase bruising. If you have visible or painful veins, it’s best to consult a vein specialist before trying cupping.

Q: Are the dark marks left by cupping blood clots?

A: No. The circular marks are usually bruises caused by broken capillaries near the skin’s surface. They typically fade within a few days to two weeks.

Q: How do I know if leg pain could be related to vein disease?

A: Leg heaviness, swelling, aching, and visible veins, especially after standing or sitting for long periods, may be signs of vein disease. A quick ultrasound exam with a vein specialist can determine the cause.
