Sorry, I beg to differ with your comment "There's no treatment for PN, and there will never be any."
There is a plethora of research and advice from major legitimate medical organizations that would disagree with you. The specific approach varies depending on the cause and severity of the condition. Treatment aims to relieve symptoms, manage the underlying cause, and prevent further nerve damage.
However I ask that, if you don't believe me, please log onto mayoclinic.org and search for "Peripheral Neuropathy". Scroll down to "Treatment" and see what Mayo recommends.
P.S. This response was not meant to be rude however individuals recently diagnosed with PN need to know there are good treatment options and not to give up!
