Welcome @gotosarah, I'm glad you found Connect. You are definitely not alone and hopefully you can find some answers and learn from others experiences. I have idiopathic small fiber PN that developed gradually over 20+ years so I can imagine how you must feel to have all of this change over a short period of time. There is another discussion where you can meet others discussing polyneuropathy and learn what they have shared.

--- Idiopathic Polyneuropathy: My endless journey to a near-diagnosis: https://connect.mayoclinic.org/discussion/idiopathic-polyneuropathy-my-endless-journey-to-a-near-diagnosis/.

Another site that you might want to bookmark for learning more about neuropathy and things you can do to help yourself is the Foundation for Peripheral Neuropathy - https://www.foundationforpn.org/living-well/.

Can you give us an update after you meet with your doctor next week?
