In what way have you felt strange?
And you have felt this way every day for several months?
Did you develop a herpes sore?
It would be extremely unusual for the symptoms that you describe to be due to HSV2.
It is very unusual for herpes symptoms to develop the day after an exposure, The average time to onset of symptoms is about 4 days after exposure It is possible for the symptoms to start as soon as 2 days after exposure, but it would be very difficult for the virus to grow at a speed to allow for onset of symptoms the day after exposure.
It also would be very unusual for symptoms to be present most days of the next 3 months after exposure, even if not on Valtrex, but it would be even less likely if taking Valtrex.
Since the symptoms are atypical for a new infection from HSV2, it is not surprising that the blood test for HSV2 antibodies is negative.
When symptoms develop a day after an exposure, it is more often due to an inflammatory reaction, and it is possible that this inflammatory reaction is causing an exacerbation of the pre-existing HSV1 infection. The rash that you describe could be due to the inflammatory reaction.
Do you have a picture of the rash?
I am sorry, but when you said that you felt oozing at the top of the buttocks and a rash, I thought that the rash was near the sensation of oozing.
Assessing the rash is an important step in identifying what type of inflammation may be present. It may be necessary for you to see your doctor when the rash is present.
