You have my deepest sympathy for having shingle is the worst, more pain than I thought possible when I first got them. A cool breeze or a cotton tee shirt lit me up. The VA offered me the shingles vaccine and I got it, after my last episode on my forehead and eyelids. The doc said it could affect my eyes so I got the shot. I been clear so far. But damn pard I hope you get cleared up soon. Be safe and Godspeed.
The risk to eyesight from shingles is substantial, as my poor vision indicates.
