Transcutaneous Electrical Nerve Stimulation (TENS) therapy is a treatment designed to relieve pain and enhance healing without the need for invasive procedures. This therapy involves the use of a small, battery-operated device that delivers low-voltage electrical currents through electrodes placed on the skin near the area of discomfort. 

These gentle electrical impulses help to stimulate nerve fibers, effectively blocking pain signals from reaching the brain and triggering the release of endorphins, the body's natural painkillers. TENS therapy is widely used to manage acute and chronic pain conditions such as arthritis, back pain, and sports injuries, providing immediate relief and promoting long-term pain management.
