The Dangers of Cupping Therapy: Safety, Risks & Side Effects

February 6, 2026

While cupping therapy is generally considered safe when performed by trained professionals, it’s important to understand the potential dangers of cupping before your first session. Although rare, the dangers of cupping can range from mild skin irritation to more significant risks like infection if hygiene standards aren’t met.

At Ervin Physical Therapy, we believe in transparency and patient education. Whether you are curious about this ancient technique or have been recommended it for pain relief, knowing the risks ensures you can make an informed decision about your health.

What is Cupping Therapy?

Cupping therapy is an ancient form of alternative medicine in which a therapist puts special cups on your skin for a few minutes to create suction. People get it for many purposes, including to help with pain, inflammation, blood flow, relaxation and well-being, and as a type of deep-tissue massage.

There are two main types of cupping performed today:

  • Dry Cupping: The suction is created by heating the air inside the cup (fire cupping) or using a mechanical suction pump. The skin is pulled up into the cup, but no incisions are made.
  • Wet Cupping (Hijama): This involves creating a mild suction, removing the cup to make tiny incisions on the skin, and then reapplying suction to draw out small amounts of blood.

While proponents suggest it can help remove toxins and improve circulation, it is vital to approach any treatment with a clear understanding of safety.

Common Side Effects of Cupping

Most patients who undergo cupping experience mild side effects that are actually part of the therapeutic process. However, distinguishing between a normal reaction and a danger of cupping is key.

1. Skin Discoloration and Bruising

The most recognizable “danger” of cupping is actually a common side effect: circular marks on the skin. These marks can range in color from light pink to deep purple. Unlike a traumatic bruise caused by blunt force, these marks (often called ecchymosis) are caused by the suction drawing blood to the surface of the skin. They are typically painless and fade within a week or two.

2. Mild Discomfort or Soreness

During the treatment, you might feel a tight, pulling sensation. Afterward, the treated areas may feel sore, similar to how your muscles feel after a deep tissue massage or a hard workout. This soreness usually dissipates within 24 hours.

3. Minor Burns (Fire Cupping)

In traditional fire cupping, a flammable substance is ignited inside the cup to create a vacuum before it is placed on the skin. If the cup is overheated or the flame is not managed correctly, there is a risk of minor burns. However, modern clinics often use silicone cups or mechanical pumps to eliminate this risk entirely.

Serious Dangers of Cupping and Potential Risks

While the side effects above are common and generally harmless, there are more significant dangers of cupping that can occur, particularly if the procedure is done incorrectly or in an unhygienic environment.

Infection Risk

This is the most significant concern, particularly with wet cupping. Because wet cupping involves making small incisions on the skin, it introduces a pathway for bacteria to enter the body.

  • Improper sterilization: If the cups or equipment are not properly sterilized between patients, or if the skin is not cleaned effectively, serious infections can occur.
  • Bloodborne diseases: Sharing equipment without hospital-grade sterilization can transmit bloodborne pathogens like Hepatitis B or C.

At Ervin Physical Therapy, our cupping services adhere to strict medical hygiene standards to negate these risks.

Skin Infections and Abscesses

Even without incisions (dry cupping), if the skin is compromised or if the cups are left on for too long, blisters can form. If these blisters pop and are not treated, they can become infected. In rare cases, this can lead to abscesses or deeper skin infections like cellulitis.

Scarring

Wet cupping carries a risk of scarring due to the incisions made on the skin. While skilled practitioners make very superficial scratches, improper technique or poor wound healing can lead to permanent marks.

Anemia

For individuals who undergo frequent wet cupping sessions, there is a theoretical risk of anemia due to repeated blood loss. This is why it is crucial to have your health history evaluated by a professional, like our team at Ervin Physical Therapy, before starting a regimen.

Who Should Avoid Cupping Therapy?

The dangers of cupping are amplified for certain groups of people. You should likely avoid this therapy or consult deeply with a doctor if:

  • You are on blood thinners: Medications like warfarin or aspirin make you bleed and bruise more easily.
  • You have a bleeding disorder: Conditions like hemophilia make cupping dangerous.
  • You have skin conditions: Avoid cupping on areas with eczema, psoriasis, or open wounds.
  • You are pregnant: While not strictly forbidden, cupping should generally be avoided on the abdomen and lower back during pregnancy.
  • You have a history of seizures: In rare cases, the procedure can trigger a vasovagal response (fainting).

How to mitigate the risks

The best way to avoid the dangers of cupping is to choose the right provider. This is a medical therapy that requires training in anatomy, physiology, and sterile technique.

1. Choose a Licensed Professional

Never have cupping performed by an untrained individual. Look for Licensed Physical Therapists (PTs) or certified practitioners who understand the body’s musculoskeletal system.
Our team, including Dr. Isaac Ervin, brings deep medical expertise to every session. We don’t just apply cups; we integrate them into a broader, safer recovery plan.

2. Ask About Sterilization

Don’t be afraid to ask how the clinic cleans their equipment. Do they use single-use disposable cups for wet cupping? How are reusable cups sterilized? A reputable clinic will be happy to explain their safety protocols.

3. Discuss Your Medical History

Be honest about your medical history. If you are anemic, taking anticoagulants, or have sensitive skin, let your therapist know immediately.

4. Follow Aftercare Instructions

After a session, your skin is sensitive. Keep the area covered and warm. Drink plenty of water to help flush your system. If you had wet cupping, treat the sites like small wounds—keep them clean and dry to prevent infection.
