A TENS (Transcutaneous Electrical Nerve Stimulation) device is a small, portable machine that delivers low-voltage electrical currents to the body through electrodes placed on the skin. These electrical impulses help to block or reduce pain signals sent to the brain, providing relief from various types of acute and chronic pain conditions. TENS devices are commonly used for muscle and joint pain, nerve-related pain, and certain types of headaches. They are non-invasive and can be used safely at home with proper guidance. **
