Cupping is a treatment method that may be incorporated in to your session, and is mainly used to relieve pain. Glass cups are placed on the skin after a rapid change in temperature occurs within the cup, causing a vacuum-like suction. When an injury occurs deep in the muscle, bleeding occurs, causing a deep bruise. There also may be inflammation in the area involving the congregation of sticky proteins. The combination of these elements results in stagnation of circulation to the area, resulting in pain. The vacuum formed by cupping draws up the old non-circulating stagnant blood and sticky fluids from the area, bringing them up to the surface so that healthy free circulation may be restored in the affected area. Cupping may also be used to draw toxins away from an affected area. It also may be used to aid in the circulation of lymphatic fluids.
