I have way too much experience with that disease. It is a nerve problem which manifests itself on your skin. The pain is excruciating and doesn’t respond rapidly to treatment. A buddy had shingles which started just over one eye. He said it felt like someone was driving a nail into his forehead. I thought he was exaggerating. Years later, I had the same thing and he was right! The danger for he and I was that our optic nerve in that eye could be effected possible losing sight in that eye. Fortunately, our eyesight was not impacted. My mother and a neighbor of mine have had shingles on their body. My mom was bedridden and that was terrible. My buddy is young (68) and in good shape. He’s miserable, in pain night and day even under medication. Sorry to hear about your reaction to the vaccine but it’s better than the disease.
