Have any of you run the iontophoresis treatment on your feet as well? I did it on mine and i notice that the effects/sensation on the feet is not the same as on your hands.With your hands you can feel the electric current through the hands but with the feet it feels like nothing at all. Was wondering am i doing anything wrong or if the soles of our feet are much thicker than the layer of skin on our hands that's why we can't feel it on our feet?
