Ever since I was a child I have always gotten fever blisters on my lips - like multiple at a time. My mom always said they were blisters from the sun, I am very fair skinned - but then we found out I was citric acid intolerable - and we then noticed I would get them whenever I would eat a strong amount of citric acid.
However, I am now wondering if I have Herpes 1. I have never had the blisters anywhere besides my mouth - not on any skin or genital area, but I looked up citric acid intolerable symptoms online and they said that you would only react on the inside of the mouth.
Is it pretty certain that I have Herpes 1?
