Is there any other condition that would cause perineal tingling and painful single pimples on the labia majora, other than HSV2? About 6 at a time, they appear in different genital areas, then disappear without scarring. The pimples are shiny (but no frank fluid observed) and stay for 2 wks at a time. Symptoms have lasted for 2 months now. No vaginal drainage. Two inconclusive cultures x2. Symptoms started 3 mo out of possible exposure and Igg and Img were negative. Feels much worse than it looks. Valtrex 1000 mg BID did not help. What else can it be?
