If vulvar pimples are not painful or itchy, there could be many causes. For example, some subcutaneous folliculitis may also be caused by warts. The warts are caused by low-risk HPV infections, like HPV type 6 and HPV 11 sexual infections, which can cause vulva, vagina and cervix, to appear as grayish-white cauliflower-like superfluous organisms. The redundant organisms themselves are not painful or itchy and can occur with a history of high-risk sexual activity or multiple sexual partners. It is recommended to go to the hospital for laboratory tests to find out if HPV type 6 and HPV type 11 are positive, which can basically confirm the diagnosis. Treatment by laser, or surgery is recommended. Since the disease is contagious, after treatment, clinical laboratory tests, no intercourse is allowed until it reaches negative.
