The Wahl Swan Trigger Point Massager makes it easier to apply pain-relieving vibrating /compression massage directly to hard, knotted trigger points anywhere they occur; breaking up tension even in the hardest-to-reach muscle areas. The pressure delivered to the body muscles helps to maximize the flow of oxygenated blood and to restore muscle functions. The Swan Trigger Point Massager helps soothe stiff muscles, relieving discomfort and reducing soreness caused by tough workouts, sedentary sitting or everyday stiffness. Use it to treat a recurring injury, after an active afternoon or a long day at the office.
