>Because neurectomy of a sensory nerve is often followed, months later, by the emergence of new, more intense pain, sensory nerve neurectomy is rarely performed.

You can't just cut a )sensory) nerve, because the pain will return later and possibly worse, why?
Can you cut more nerves afterwards to the point where pain doesn't return? Do you get some kind of "phantom" pain then?
