the settings you will have to experiment with. i change the settings depending on how im feeling.

duration of 20-30 minutes.

at first i was treated with a professional unit at a podiatrists office. the placement of the electrodes was above the area being treated, like ankle area for feet, wrist for hands etc. now i use the electrodes in a divided foot bath with one electrode on each side. the reason i do this is that my feet are so numb that i wont feel the electricity if i just attach the electrodes to my skin without the water. its safe, just put one lead in each side and one foot or hand in each side. its the same basic concept as what the rebuilder did as far as using a footbath.

as far as pain intensity, the treatment doesnt hurt if thats what you mean. if you mean how do pain levels react, it reduces the pain while you are using it and longer term treatment leads to permanent reduction of pain even when you are not using it. not elimination but reduction. how much would depend on the person and what type and cause of PN they have.

wether it would work for you i cant say. if you go to a podiatrist or physical therapy place that has it, you could try it. their unit would be stronger than the home unit.
