Sometimes it goes away, and sometimes it's a permanent problem, from what I've read. With my dad's first cancer, it went away after a few months at the end of chemo. With this cancer, it is still a problem in his feet, but not as bad. I read that the antidepressant Cymbalta may also be helpful in dealing with the CIPN. Maybe that's something to look into. http://www.cancer.org/cancer/news/news/study-shows-duloxetine-reduces-pain-from-chemotherapy
