That sounds pretty harsh which probably translates into the alternative being even harsher. Wow. I have a small RF burn in one of my fingers, about 3 mm across and as deep as the bone, it never healed properly (I got it when I was 17, a long time ago from a Tronser trimmer that I touched by accident in a 1KW FM transmitter). I hope that your treatment does not leave such marks.

Apparently the 'pulsed' version of your treatment is to keep the temperature down while still having the same effect on the nerve.
