The pads must be moist and sticky to work. Pads that are not moist enough will produce a weak and stinging sensation. Before each use dip your finger into water and rub the water onto the massage pads. Apply the pads immediately to your skin when they are still wet. Make sure that the pads are making full and firm contact with the skin. Worn out pads may also cause a stinging sensation. Replace the pads as needed.
