Cupping is a technique where glass, silicone, or plastic cups are applied to the skin with suction — either through heat (traditional fire cupping) or a manual pump (modern silicone cups). It has roots in traditional Chinese medicine and Middle Eastern medicine going back thousands of years.
What it does mechanically
The suction lifts skin, fascia, and superficial muscle away from the underlying tissue, creating a decompressive effect opposite to massage's compression. This can:
- Increase local blood flow
- Reduce muscle tension and trigger point activity
- Improve tissue mobility and gliding between fascial layers
- Modulate pain through neurological input
What the research says
Evidence is moderate for chronic neck and low back pain, tension headaches, and shoulder and knee osteoarthritis. It's not a magic bullet, but it's a legitimate tool alongside other manual therapy when applied thoughtfully.
What the marks mean
The circular discoloration left by cups is called petechiae — small capillaries in the superficial tissue release blood into the surrounding area. This isn't bruising in the traditional sense and doesn't indicate injury. Darker marks may suggest more chronically restricted tissue in that region. Marks typically fade within 3-10 days.
When we use it
- Chronic muscle tension that hasn't fully responded to compression-based therapy
- Trigger points in the upper back, low back, and IT band region
- Post-workout recovery
- As part of a broader plan alongside adjustments, exercise, and other soft tissue work
When we don't
Over open wounds, active infections, deep vein thrombosis, on skin that bruises very easily, or on patients on blood thinners without physician clearance. Also not appropriate as a stand-alone treatment for structural issues that need other interventions.
What to expect
Static cups sit for 5-15 minutes. Sliding cups are moved across oiled skin. Sensation is a strong tug, not painful. Marks appear and last a few days. Most patients feel a distinct release afterward.
Cupping is one of many tools we use. If you're curious whether it's right for your case, ask at your next visit — we tailor techniques to what your tissue actually needs.
