Why do I, on occasion, feel stinging sensations from the HiDow pads?
Each pad must be moist and sticky to work. Pads that are not moist enough, will produce a weak and stinging sensation. Before each use, ensure that you dip your finger into some clear water and rub the water onto the Hi Dow massage pads. While the HiDow pads are still wet, apply immediately to your skin. Make sure that the pads are making firm and full contact with your skin. Worn out pads may also cause a stinging sensation. Replace the HiDow pads as needed. Even when you feel stinging sensations, the HiDow Electronic Massager is not harmful to use. You just need to ensure that the pads are moist before each use.
