Hello @frankie7, Welcome to Connect. There have been a lot of members posting about neuropathy symptoms after getting the COVID-19 vaccine. I have small fiber peripheral neuropathy and have completed both Pfizer COVID shots with minimal side effects that a majority of people who took the vaccine also had - sore arm and extreme fatigue following my second shot. It did not cause my neuropathy symptoms to flare or worsen.

I think your neurologist may just be confirming his thoughts on the possibility of diabetes but that would be a great question to pick up the phone and ask your neurologist. Here's more information on the tests:
