It is very clear that at some point in your childhood you acquired HSV one orally from an adult kissing you with a cold sore. That is why the number is substantial and it merely indicates that you have mounted a successful immune response to HSV one. Many people who test positive for HSV one do not report cold sores or sores inside the nose which is a common place for recurrence. Taking acyclovir is probably not necessary at this time if you’re not symptomatic.
