Hi Lorena @rnlorena, Welcome to Connect. To have the neuropathy develop overnight seems really strange and rare. I have idiopathic small fiber peripheral neuropathy and it started gradually more than 20 years ago. I can relate to being stressed out and having a lot of questions you are trying to get answered.

One of the best sites for neuropathy information is Neuropathy Commons - https://neuropathycommons.org/. Also, for diagnosing the different types of neuropathy, Dr. Matthew B. Jensen has some really good and easy to understand videos on his YouTube channel - https://www.youtube.com/c/matthewbjensen

You mentioned having pain in your eyes. Is it like a migraine headache or is it the actual eye that is painful?
