I was diagnosed with Shingles Jan 2025. I had it on the right side of my face. I had shingles of the cornea and my eye burned terribly. That is resolved but I have itching and burning on my forehead , etc eyebrow right eye and right part of scalp. I am on 900 milligrams of gabipentant. . I don’t think it is helping anymore. I am seeing a neurologist this Wed and I hope he has a solution. I don’t have Afib . Can’t help there . Wish you well
