Based on TCM theory, pain occurs when Qi and blood are blocked while flowing through meridians, or when there are deficiencies of Qi and blood to nourish internal systems. TCM treatment is described as a combination of acupuncture, acupressure (Tui Na) and herbal medicine to remove blockages between the meridians and restore balances. In addition, acupuncture has been proven as a drug-free, safe and effective method for pain relief.
