Have you ever noticed circular, reddish marks on an athlete’s shoulders, back, or legs and wondered what they were? Popularized by elite swimmers and professional athletes, those distinct circular marks are the result of cupping therapy (also known as myofascial decompression).

At our physical therapy clinic, we use modern cupping techniques to help patients reduce muscle tension, break up scar tissue, and speed up recovery from chronic pain or sports injuries.

In this guide, we break down how cupping therapy works, why it benefits your muscles, what those circular marks actually mean, and what to expect during your physical therapy session.

What Is Cupping Therapy?

Cupping therapy is a manual physical therapy technique that uses specialized silicone, plastic, or glass cups to apply negative pressure (suction) directly to the skin and underlying muscle tissue.

Unlike traditional massage or deep tissue work, which presses down into the tissue (positive pressure), cupping lifts and stretches the fascia and muscle tissue upward (negative pressure). This suction creates a vacuum effect that:

• Decompresses tight muscles and restricted myofascial layers
• Increases localized blood flow and tissue circulation
• Hydrates dry, restricted connective tissues (fascia)
• Stimulates natural lymphatic drainage to clear inflammatory waste

The Evolution of Cupping

While crude forms of suction bodywork date back thousands of years, modern cupping therapy used in outpatient physical therapy is grounded in Western neuroanatomy and sports medicine. Physical therapists use targeted decompression to restore tissue gliding, reduce joint stiffness, and enhance movement patterns.

What Are the Main Benefits of Cupping Therapy?

Physical therapists frequently integrate cupping into broader rehabilitation programs for its rapid effects on pain relief and mobility. Key clinical benefits include:

• Alleviating Muscular Tightness & Knots: Decompresses tense muscle fibers and taut bands.
• Breaking Up Scar Tissue & Adhesions: Helps remodel restricted tissue from previous surgeries, tears, or chronic overuse.
• Improving Joint Range of Motion: Restores sliding capacity between fascial layers, allowing for smoother joint movement.
• Accelerating Post-Workout Recovery: Surges oxygenated blood to fatigued muscles to clear cellular metabolic waste.
• Reducing Acute & Chronic Pain: Modulates local nerve signals, providing rapid relief for back, neck, and shoulder pain.

Cupping Marks vs. Bruises: What’s the Difference?

One of the most common concerns patients have is whether cupping causes painful bruising. While cupping marks look similar to traditional bruises, they are physiologically very different:

• Traditional Bruises: Result from direct blunt force trauma that ruptures blood vessels and damages soft tissue. Bruises are usually tender to the touch and change colors as they heal.
• Cupping Marks: Caused by negative pressure bringing stagnant blood, cellular waste, and fluid up from deeper tissue layers to the surface of the skin. They indicate a release of tissue congestion.

Key takeaway: Cupping marks should not feel painful to press on. They typically fade on their own within 3 to 7 days, depending on your circulation and hydration levels.

What Conditions Can Cupping Therapy Treat?

Cupping therapy is an effective modality for a wide range of neuromusculoskeletal conditions, especially when combined with active physical therapy exercises and manual care:

• Low Back Pain & Sciatica: Relieves stiffness in the lumbar erectors, gluteal muscles, and thoracolumbar fascia.
• Neck & Shoulder Tension: Eases tension headaches and chronic upper back stiffness caused by desk work or posture strain.
• Plantor Fasciitis & Achilles Tendinopathy: Mobilizes tight calf muscles and restricted foot fascia.
• IT Band Syndrome & Knee Pain: Reduces friction and tension along the lateral thigh and surrounding knee joint structures.
• Post-Surgical Scar Tissue: Mobilizes healed surgical incisions to prevent deep tissue binding.

Types of Cupping Techniques Used in Physical Therapy

Your physical therapist will select the right cupping technique based on your specific injury, pain level, and recovery goals:

1. Static Cupping: Cups are applied to specific muscle knots or trigger points and left in place for 3 to 5 minutes to decompress a focused area.
2. Gliding / Sliding Cupping: Massage cream or lotion is applied to the skin, allowing the therapist to slide the cups along the entire length of a muscle band (e.g., along the IT band or back muscles) for dynamic tissue release.
3. Dynamic Movement Cupping: Cups are placed over tight tissue while you perform active, guided movements (such as squatting, reaching, or rotating). This trains your nervous system and muscles to move freely through a full range of motion without pain.

What to Expect During and After Your Session

Before & During Treatment

• Your physical therapist will expose the target area (such as your back or shoulder) and apply a gentle lotion or oil.
• You will feel a firm pulling or stretching sensation, but the treatment should never be sharp or painful. Always communicate with your therapist so they can adjust the suction level.

After Treatment Tips

• Hydrate Well: Drink plenty of water following your session. Rehydrating helps flush out metabolic waste products lifted during treatment.
• Avoid Heavy Workouts Immediately After: Give your body a few hours to settle before engaging in intense weightlifting or strenuous exercise.
• Keep the Area Covered: Protect the treated area from cold winds or extreme temperatures immediately following your appointment.

Frequently Asked Questions (FAQ)

Does cupping therapy hurt?

No. Most patients find cupping therapy to be soothing and relaxing, describing it as a deep, lifting sensation rather than a painful pinch. Your therapist can easily adjust the suction to match your comfort level.

Is cupping therapy covered by insurance?

Yes! When performed by a licensed physical therapist as part of a medically necessary rehabilitation program, cupping is often integrated into manual therapy billing codes. If your therapist believes you will benefit from cupping, then it is also included in our self pay rate.
