The condition is likely to be folliculitis of the vulva, especially in the pubic hair area. This is mainly due to a lack of local cleanliness and hygiene, resulting in the formation of a conditional pathogenic infection or a local skin breakdown and secondary infection, eventually resulting in the symptoms of folliculitis. It is also possible that other factors may cause secondary infection in the vulva area due to skin breakdown, such as local soft tissue infection after skin breakdown. In addition, there is also the possibility of genital herpes, which, if present, may also appear as blisters on top of erythema in the genital area, with varying degrees of infiltration and pain.
