Ba Guan (cupping) is generally considered safe when performed by a trained practitioner. While most people experience minimal discomfort during the treatment, the suction can create a sensation of tightness or pulling on the skin.
It is common to see circular marks or bruises, and sometimes small blisters on the skin after a cupping session, which may last from a few days to a week, but these are usually harmless and indicate the therapeutic effects of the treatment.
However, if you have certain medical conditions (such as skin infections, open wounds, or bleeding disorders), it's essential to consult with your healthcare provider before undergoing cupping therapy. Open communication with your therapist during the session can also help ensure your comfort and safety.
