‘Red circular marks’
In oriental medicine (TCM), cupping therapy is known to be particularly effective for relieving pain and muscle tension, and promoting local circulation.
Special glass cups are placed on the skin of the affected region to create suction pressure for a short period of time. It is thought that intense sensation on skin, fascia, and superficial muscles generated by suction force provides strong therapeutic stimulus to the nervous system that regulates our joint structures including muscles, tendons and blood vessels, thereby, inducing therapeutic effects.
However, because of the suction force applied on the skin, tiny blood vessels of your skin may burst and cause slight bruising. This it will leave red circular marks temporarily which will generally disappear spontaneously within a short period of days.
