Wait, you have pus coming from a lymph node? Are you sure? I certainly hope you had that evaluated.
Your symptoms do NOT sound like herpes to me, and the provider who saw you and did the PCR should be in a far better place to know if this looked like herpes. Also, herpes lesions don’t last five weeks.
I am extremely concerned that you have pus coming out of a lymph node – not because of herpes but because this would be EXTREMELY rare and concerning.
Have you looked at pictures of something called mollusum contagiosum? Could the lesions be that.
You could do another IgG test just to be more certain if you are still concerned or the western blot for greater accuracy
