If there is a hard bump next to the vagina, which is not clinically painful, it is often caused by a vestibular gland cyst, mainly due to inflammation of the vulva or long-term inflammatory stimulation of the vagina, causing an obstruction of the vestibular gland ducts and the formation of a local cyst. This cyst is often clinically asymptomatic and is discovered when the vulva is cleaned or unintentionally, but once the infection is combined it can cause severe pain and even form an abscess, requiring incision and drainage surgery. The most important thing is to have a good understanding of the situation.
