Our period cramp relief device is a TENS machine - that’s Transcutaneous Electrical Nerve Stimulation if you want to get fancy. Our device works by applying a small electrical current through two compression pads (the Love Handles) that are placed over nerve roots that supply the sensory fibres to the uterus and/or lower back. Once in place, the stimulation prevents pain signals from travelling to the brain, causing the muscles in the uterine area to relax and resulting in a calming analgesic effect
