TENS Unit from Titan Medical
“TENS” is the acronym for Transcutaneous Electrical Nerve Stimulation. A “TENS unit” is a pocket size, portable, battery-operated device that sends electrical impulses to certain parts of the body to block pain signals. The electrical currents produced are mild, but can prevent pain messages from being transmitted to the brain and may raise the level of endorphins (natural pain killers produced by the brain).
Cost is covered by most insurance carriers.
