why do vaginal bumps appear
Vaginal bumps can be a sign of genital herpes. The most common STD that produces bumps on the vagina or skin in the genital area is herpes type 2. Herpes outbreaks are characterized by a cluster or close grouping of small, round blister-like spots that occur in the genital region (any skin that would typically be covered by shorts).
The most common condition leading to vaginal bumps is folliculitis. This is a skin infection at the base of a hair follicle, much like a pimple. It can occur anywhere on the labia and is quite tender, but it's nothing to be concerned about. Bartholin cysts form at the bottom of the vaginal opening.
