Hi and welcome to HCM.
Hepres type 2 is causing genital infections in most cases so probably in your case too.Type 1 But it isnt even matter because it has the same symptoms an dis treated on the same way. Steroids
wouldnt give false postive results. I suggest to take some of the antiviral
creams or medicines. it should pass on such treatment and your partner should be treated as well. WIsh you good health.
