A negative IgG at 12 weeks out suggests with 92% certainty (as compared to western blot) that you are not infected with HSV 2 and 70% that you don’t have HSV 1. If you want to know if you have HSV 1, you should do the western blot. And if you do the blot and it is positive for HSV 1, you cannot know if your infection is oral or genital. I think it is important that your doctors do not think the presentation you describe is herpes.
The other thing is, if you test positive by western blot and continue to test negative by IgG, you cannot know if your infection has been present for 3 months or 3 years.
