I'm pretty sure i have vaginal herpes and may have had in the past but they've never been an issue. the last 3 days have been agony. is there any over?

Genital herpes?: Something doesn't compute. Only initial herpes, i.e. the first infection, is likely to cause "agony". Maybe not herpes before, but now a new infection? But several other possibilities as well. The only way to get answers is to see a doctor in person, preferably one with lots of experience in herpes and other STDs. Do it ASAP, sooner the better for accurate herpes diagnosis and effective treatment.
