Hello @addy60 -- Welcome to Connect. @19jimmy57 did give an update that his symptoms were not due to the Shingrix vaccine in a later post here - https://connect.mayoclinic.org/comment/243864/

I had both Shingrix vaccinations a few months ago but only had a little fatigue and a sore arm from both. I'm sorry to hear your experience was not good. I think each of us has to weigh associated risks. I have known folks that had shingles and it's very painful and I definitely do not want to experience shingles.

You mentioned you will be having a nerve conduction test soon. Can you provide an update after your appointment?
