Thank you Josh for your kind Reply.

I don't have any desease that may be the cause for my neuropathic pain (I did all kind of exams). My pain was dued to a stupid exercice with dumbells. However I do have small neuropathic symptoms, that are decreasing from day-to-day, that is why I'm gonna do the biopsy. Now I'm affraid I'm the one who is prolonging that pain (with my mind, stress, etc...)

Anyway, what I wanted to know is that: reenervation of small fibers on the skin after a nerve lesion, means that the pain should stops.

By the way how did they find your idiopathic pain?
