How exactly were you diagnosed and with which type, HSV 1 or HSV 2?
I think your dose is way too high for continuous use.
It would be useful if you had genital swabs for HSV when you are having these symptoms. Not everything that happens in the genitalia of people with HSV are HSV symptoms. You are assuming the symptoms are herpes and that Valtrex isn’t working but that may not be accurate – a swab test would tell you if taken when you are experiencing these symptoms
