I'm negative for HSV-1 and HSV-2. So I had a spot on my labia that looked like classic herpes, and I've had spots on my lip since I was a little kid that tingle and look like cold sores but aren't. Obviously I've never bothered to be tested for HSV-1, but I've had people with cold sores and doctors tell they looked like them. And they predated my acne, so while now they could be weird pimples, I don't think they always were.
Are there any other types of skin conditions that act like this? Should I be suspicious of my blood test for either virus? If I had cold sores as a kid but haven't in a decade or so, could my antibodies be low enough to not trigger a positive?
