It does work for PN, specifically in the feet. As it was explained to me, the Marcaine numbs the area (the more numb you can stand it and still be able to walk, the better) but the main purpose is to open the ion channels of the nerve cells. Then you receive moderate electrical stimulation that promotes healing. Those two steps are supposed to work very well in combination as opposed to one without the other. The clinic where I tried this treatment had an 85% success rate of permanently reducing or eradicating the numbness or pain.

I had thought it might be painful because on the two occasions last year that I had a steroid injection and then the EMG, my nerves got all fired up and caused me additional pain than beforehand. But I did not experience that with this treatment. The clinic where I went has not experienced any negative responses to this treatment, only no results in 15% of the patients who try it.
