What is TENS?
TENS stands for Transcutaneous Electrical Nerve Stimulation and is a method of pain relief involving the use of a mild electrical current.
How does it work?
A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes. These pads are placed directly onto the skin, near the source of pain. When the machine is switched on, small electrical impulses are delivered to the affected area of the body and are felt as a tingling sensation.
