@laureen8844, I don't recall experiencing any weakness associated with small fiber neuropathy. Most of the weakness I've experienced since I was diagnosed with SFN is more related to the aging process and a somewhat sedentary lifestyle before I was diagnosed. I've been more proactive since being diagnosed and I think that has helped with my overall health. I still have some issues with my core strength which I'm working on but have a long way to go 😊
