Hi Heldo
Welcome to NeuroTalk; I hope that you will find the community as knowledgeable and supportive as I have

.
There are many possible causes of peripheral neuropathy and unknown (idiopathic) causes are common.
If you share your story in the PN forum (
https://www.neurotalk.org/forum20/) I am sure that you will get helpful responses from other members.
Best wishes.
