I hope your doctor took a swab specimen from your
genital lesions
for HSV testing by culture or PCR. That test is recommended
for every person with
genital ulceration, regardless of whether the provider suspects herpes. If so, that result may answer the question. If not, or if such a test is negative, you should go on to have a blood test. If you have a negative IgG antibody test for HSV that becomes positive in a few weeks, that also would nail down a herpes diagnosis.
