Hi @mogden52 (PricklyPear), welcome.
I moved your post to this existing discussion:
- Non-Length Dependent Small Fiber Neuropathy: https://connect.mayoclinic.org/discussion/non-length-dependent-neuropathy/

I did this so you can read previous posts and connect easily with other members like @kathleen123 @ncameron @sf2021 @gator66 @exitframeleft @johnmacc @trudi22 @rnlorena @jemock @danye1 and more who have experience with Small Fiber Neuropathy (Non-length Dependent). Given that you are in the early stages, they may be able to offer thoughts about progression, although, as you know, everyone is different.

You mention that you are working on getting to the root cause and are currently exploring autoimmune causes. Have you been diagnosed or are living with an autoimmune condition?
