TENS(Transcutaneous Electrical Nerve Stimulation) is a well-known method of electrotherapy which is used for curing acute pain. It is highly user-friendly and is hand-held and battery charged. A number of these units have two wires with pads called electrodes on ends which go within the skin, on the area causing pain. It is also safe to use and doesn’t cause any sort of pain in the way prescription drugs do. There are no risks of burns, irritation or overdose once you start using TENS.

TENS is highly effective in curing short term as well as long term chronic pain. Studies conducted by researchers have shown that using TENS can help people to overcome muscle as well as nerve pain. But one thing which you need to keep in mind is the fact that all TENS units are not of the same type. The most common ones use patches which you will have to place on your skin. There are also some acupuncture like TENS units which use tiny needles to let currents enter the skin. Both these types cause no pain.
