Just been diagnosed - rash on cheek (near eye) and scalp. It's not that painful but I've been googling (of course) and see that the most common complication is neuralgia, especially if the rash is on the face near they eye. I remember my sister having neuralgia years ago and the pain was awful and made her cry and there didn't seem to be any treatment, and from the looks of it there isn't much now. I know I shouldn't be stressing about something that hasn't happened.........anyone got any experience.
