Neck Shoulder Wrist Self-Heating Patches

Thermacare Self-Heating Patches provide effective, targeted relief of muscle and joint pain associated with muscle strain, muscle aches or osteoarthritis. They can be placed on the neck, shoulder or wrist. They have multiple cells that contain air-thermoactive agents, such as iron. As soon as they are applied to the skin, they diffuse constant heat for 16 hours, which relaxes the muscles and thus relieves pain.
