Cupping therapy side effects: what to expect

Cupping marks are the most common concern for first-time clients. They look like bruises, circular, dark red or purple, occasionally dark brown. They are not bruises.

A bruise is caused by trauma: blood leaking from damaged blood vessels into surrounding tissue. Cupping marks are caused by decompression: the negative pressure of the cup draws blood to the surface through capillaries that are intact but fragile from chronic restriction. No tissue is damaged. The blood remains within the vascular system.

Darker marks (deep purple, almost black) indicate areas of greater chronic restriction, the tissue in those areas has less circulation and more fascial compression. Lighter marks (light pink, red) indicate better tissue quality. Colour provides useful information about where restriction exists in the posterior chain.

As the tissue quality improves with repeated sessions, marks become progressively lighter. Experienced practitioners use mark colour as part of the clinical picture.

Marks typically fade within 3–7 days. They do not hurt the way bruises do, there is no tenderness on palpation after the session. Some clients report a warm, pulling sensation during the session and mild soreness 12–24 hours afterward, similar to post-exercise soreness. This is normal and resolves within 48 hours.

Cupping should not be applied to: active skin conditions (eczema, psoriasis, open wounds), areas of acute injury or active inflammation, over bony prominences, to clients on anticoagulant medication (increased bruising and bleeding risk), or during pregnancy (certain points).

Clients with a history of skin sensitivity or easy bruising should inform the practitioner before the session.

Stay hydrated for 24 hours post-session. Avoid very hot baths or intense sun exposure on the treated areas for 24 hours. Light movement is encouraged, the improved circulation benefits from activity. Avoid alcohol for 24 hours.

If soreness is more than mild or persists beyond 48 hours, contact the clinic.
