I'm worried that this might be herpes, though from my research, I really can't tell.
Two days ago, I used a new type of menstrual pad that came in a carboard box rather than sealed in a plastic wrapper, and the next day there was a thin line running down both labia majora where the skin was irritated and peeling. So I thought it was pad rash. This morning, upon further examination, I noticed that just outside my pubic area between my vulva and buttocks there was a dry red patch on one side and a small, bright pink bump on the other. So far, the bump doesn't hurt or itch like cold sores, but the dry red patch itches and is peeling.
I really hope this is contact dermititis or something else that will go away, but I'm really scared that it's herpes. What do these symptoms usually indicate?
