Cupping has been used for thousands of years to ease the pain. During a cupping treatment, your provider will place cups on the area being treated, causing a vacuum or suction to pull the skin upwards. The suction force expands and opens tiny blood vessels known as capillaries under the skin. Your body will treat this area like an injury drawing more blood flow to the area to stimulate your natural healing process. Cupping is used for a variety of symptoms such as arthritis, back pain, neck pain, knee pain, shoulder pain, and a variety of others.
