And initial oral herpes usually causes not only sore throat
, but also multiple sores in the mouth, i.e. of the cheeks, gums
, etc. Equally important, herpes doesn't last this long; even without anti-herpes therapy, your symptoms would have cleared up entirely long before 3 months. Finally, you are exactly right about genital symptoms: in someone who has had both vaginal and oral sex with someone from whom they catch herpes, it is unusual to become infected only orally.
