After a bit of digging, I came across this older post from HHH, which may have some bearing:
"Most important, there is no risk of HSV-2 infection from kissing. Although it is theoretically possible to get either HSV type at any anatomic site, oral HSV-2 infection is exceedingly rare. You can safely assume your GF's HSV-2 infection is strictly genital. If it happens that your GF also has (oral) HSV-1 and you do not, then there is a potential risk you could acquire genital herpes due to HSV-1. But that is an unlikely outcome; statistically speaking, the odds are strong you already are HSV-1-positive, as most people are. " (

At heart, I think the physician involved with my partner isn't an expert, is making possibly incorrect assumptions (patient has some sort of outbreak on cheek, HSV test comes back positive for HSV 2, ergo she has HSV 2 on her face) when it could be an HSV 2 genital infection, and a case of HSV 1 or genuine shingles on the cheek.
OR -- in the best of all worlds -- the initial test was a false positive for HSV 2, my partner has, perhaps, HSV 1, and had either that or a shingles outbreak on her face.
Lord, these scenarios get complicated.
