TENS, or transcutaneous electrical nerve stimulation, is a back pain treatment that uses low voltage electric current to relieve pain. TENS is typically done with a TENS unit, a small battery-operated device. The device can be hooked to a belt and is connected to two electrodes. The electrodes carry an electric current from the TENS machine to the skin. Call us (704)503-9338 https://www.webmd.com/back-pain/guide/tens-for-back-pain
