Hi Max,
Can you really diagnose polyneuropathy with a tuning fork? Why is a practitioner using a tuning fork in 2021? How sensitive and reliable and reproducible are those tests? You have no base line data to work with. What was your sensitivity like 10 years ago for example?

I have several of those symptoms you describe form time to time and they are not the end of the world. I barely notice them.
Peripheral nerves are able to heal themselves so adopt the optimum lifestyle for nerve health if you are worried by Peripheral Neuropathy. Diet, supplements, exercise, meditation, gratitude practises, for example.

Best wishes,

Atty
