Salonpas Pain Relieving Patch: Large, 5.12" X 3.31", 6/Box

These external patches deliver relief directly to the area of the body that needs it, without affecting other parts of the body. Medicated patch is applied to the outer layer of the skin and works its way through the layers of your skin. It then enters the bloodstream through the capillaries where it acts immediately to relieve strains, sprains, bruises, aches and arthritis.
