A TENS machine is a small, portable device with a battery. It has wires with sticky pads that you put on your skin.
A healthcare professional, such as a GP, physiotherapist or midwife can advise you if you're not sure where to put the sticky pads. They can also tell you about alternatives if your skin is sensitive to the sticky pads.
If your skin becomes itchy, irritated or red (redness may be harder to see on brown or black skin), turn off the machine and remove the pads.
