Thumbs down on this treatment from everything that I've read as well......

Quote on this from Dr. Hooshmand:

Because the Radiofrequency damage causes high temperature in the adjacent areas of the target, it also destroys the adjacent normal nerves causing a much larger lesion and scar formation with spread and aggravation of pain in a permanent fashion.

Not enough good data / results and way too much risk to consider this treatment in my mind. And you are hearing less and less about it as time goes by.
