Embarrassing question

I'm a pre-pharmacy student and I get cold sores 1-2 a year. Are there any health policies that would restrict where I work in the future? Also, if I were working in retail, would I be allowed to work if I had a blister? It's very embarrassing to even ask this question, but it would be worse if I waited until after school to find out. I do manage it with valacyclovir and Abreva, but sometimes there is no warning until the blister appears.
