My EMG and nerve conduction study came out showing no long fiber neuropathy. The fact that my symptoms of tingling (pins/needles) and numbness are at the furthest areas of my body, fingers and toes, there the nerve fibers are at their smallest makes it small fiber neuropathy. Think of a limb at its thickest…that would be the closer to your spinal column. As the nerves branch out, they become smaller. Hence the smallest at the finger tips and toes.
Definitely tell your doctor about my case, especially if your symptoms started about 2 months after starting the Rosuvastatin 20 mg like it did with me. As it got progressively worse is when I went to seek help and stopped taking the rosuvastatin. That was afterabout 5-6 months of taking it. It’s been 6 weeks since I stopped taking it, and I’d say I’m 50-60% better already!
Wishing you the best of luck!

Good evening, @allegheny and @janteel. I just noticed your question about small fiber neuropathy. In my experience, a skin biopsy in the ankle area is the best and most accepted way to diagnose small fiber neuropathy. My neurologist also insisted on a brain MR I . Evidently, some older folks like me need to prove that their brain is still working appropriately.

I think that my skin biopsy was sent to a special facility in Texas for the diagnosis. I recall how sad my neurologist's voice was when he relayed the information about the evidence of small fiber neuropathy.

Good luck with the rest of your "hunt". Let me know what you find out and how you decide to control what the biopsy revealed.

May you be safe, protected, and free from inner and outer harm.
