Transcutaneous nerve stimulating apparatus wherein a portable, battery-operated variable pulse width, variable pulse rate oscillator is coupled through a variable amplitude current amplifying device to a set of electrodes adapted to be positioned upon the skin of a patient in proximity to a pain exhibiting area. The electrical signals or impulses are transmitted through the skin to the underlying nerves and serve to block the pain.
