If one already has painful neuropathy or whatever underlying conditions before taking the Covid vaccine, it is not a convincing argument (for lack of a better word) to take a vaccine that could stir up/stimulate the immune system to reignite or possibly worsen the symptoms of that underlying condition. Even if an asymptomatic "underlying" condition exists, it would appear the vaccine is still a LINK to that condition changing from asymptomatic to unfortunately symptomatic subsequently changing the individual's quality of life.
