Micro Current / Electro acupuncture uses extremely low-level electrical current to treat nerve and muscle pain. It restores normal frequencies with in the cells, resulting in improvements in pain, inflammation and function. The micro currents are so weak you will feel no shock-like sensation because they do not stimulate the sensory nerve. This device has a sensor that allows the doctor to see how inflamed the pressure point of concern is and exactly where the nerve is located.
