As your therapist uses the cups on your body to create suction, the suction helps draw fluids and increases circulation to the target area. The additional blood and oxygen flow to the targeted region helps relieve muscle tension, inflammation, and pain.
Oxygen-filled blood that flows through to the damaged muscles begins the healing process. Additionally, the heat in the blood flowing to the region expands blood vessels, easing stiffness, restoring movement, and thus, reducing pain.
