Myofascial Decompression or better known as Cupping, is an ancient method of alleviating muscle tightness, aches, pains, local congestion and stagnation of blood flow.
When muscles are tight or even "knotted" it will cause pain and stiffness. Blood and oxygen can not flow through as freely as they are supposed to, it builds ups and causes congestion thus causing more blockages of blood and oxygen flow.
Cupping is a partial vacuum created with glass cups and a flame and applied to the skin causing layers of skin and muscle to be pulled away from each other. Cupping has been found to work as deep as 4 inches into the skin helping to separate knots, congestion and bringing the stagnant blood and impurities to the surface, which is visible as the circles mistaken as"bruising". It is important to realise, this is not actually buising. Bruising is a result of a traumer to the skin whereas the cupping process is not traumatic or painful and the marks are painless to touch despite how they look.
Cupping is also very effective as a relaxation technique and improves circulation around the body
