Follicular sebaceous gland blockage: if the sebaceous gland secretion is exuberant, the follicular sebaceous gland blockage, the sebaceous gland secretion can’t be discharged after gathering together, which may lead to the appearance of vulvar cyst symptoms. 3. Bacterial infection: if you don’t pay attention to personal hygiene, bacterial viral infection may cause irritation to the vaginal opening, and therefore vulvar cysts may appear. 4. Chronic inflammation of the vulva or the vagina: if the patient is a woman, also consider vestibular cysts.
