TENS (Transcutaneous Electrical Nerve Stimulation) is a non-invasive medical procedure that uses electrical impulses to relieve pain. It works by sending an electric current through electrode pads placed on the skin, which stimulates nerve endings and blocks pain signals from reaching the brain. TENS devices are commonly used for chronic pain relief, such as back pain or arthritis, but they can also be helpful for acute pain conditions like muscle spasms or post-surgical pain.
