Should I Test For Herpes As I Have Slight Itching On Head And Feet?

i am in a long term relationship. not many other partners. recently i got it in my head that i could have asymptomatic herpes. then i started feeling pain and slight itching in spots all over my body -- head, feet, genitals. just an itch for a second that then goes away. what do you think?

i never had any oral anything in my life until recently had a tiny maybe cold sore. my girlfriend reports having them on occasion for her whole life, so she's probably the source of that.

i had this fear years ago and saw a doctor, he told me i had no symptoms and ordering thr test could show whether i had ever been exposed but he didn't recommend it because "what are you gonna do with that information"

do i need to be evaluated for a genital herpes infection?
