I don’t think additional testing for HSV 2 is going to help you at all. And your symptoms do not sound herpetic in any way. Everyone has small bumps on the thighs or buttocks from time to time and the vast majority are not herpes. If you want to be clearer about HSV 1, you could get a herpes western blot as the screening test misses about 27% of HSV 1 infections. But even if your HSV 1 western blot is positive (and we can order this for you from our clinic), it doesn’t mean that your genital symptoms are genital HSV 1 infection. Red scrotum syndrome does sound like what you have and I don’t fully understand what causes that – we have patients who have it and it is very annoying for sure.
I’m seriously thinking that herpes is NOT your problem here.
