Herpes lesions can go away in three days, yes, but the normal time for healing is about a week. there is a good deal of difference between individuals in regards to lesion healing time.
Question 1. You said I should swab it, but you also said you doubt it’s herpes. Can you please tell me why you doubt it’s herpes. That information would really interest me.
Because this is an unusual place for a herpes outbreak to show up.
Question 2. Does the information about the last time we had sex, 30 days ago, and the onset of symptoms sound like herpes?
That is a long time after last exposure for symptoms to show up, definitely. Normally, if people are going to develop symptoms after first infection, they do so within 2-10 days, with the average being 5.5 days.
Question 3. Do you think there is still a good chance she is a false positive if she never had hsv1, chicken pox etc.?
Yes, I think there is an excellent chance (85% chance) that this is a false positive (which means there is a 15% chance it is a true positive, of course)
