My DH got it above one eyebrow...got the worst headache of his life the day it showed up. I took him to the ER. They of course thought it was a stroke, so did a CT scan of his head. Never even mentioned shingles.
The next day I went to work & told coworkers about the mark & headache. They told me get him to the pcp asap, that it was probably shingles.
He got there right away, and yep. Took the med & he had no problems.

But tell me-why didn't the ER doc even consider shingles???
