Vestibulitis is a condition in which the vestibular glands located at the posterior part of the labia majora on both sides are infiltrated by pathogens and cause inflammation. The process of its development is divided into the following stages. First, during intercourse, some pathogens are spread, especially streptococci, staphylococci, E. coli and anaerobic bacteria. Sexual transmission brings most of the bacilli-like bacteria, which are more capable of residing in the vagina and cause a greater chance of infection. In fact, the glandular ducts of patients who already have vestibular adenitis can become red and swollen, and the duct opening may become blocked. If the inflammation worsens, the entire gland becomes a lump and the patient will noticeably feel a burning sensation due to the swelling in the pubic area and even experience intense pain. Occasionally, there may also be difficulty in passing urine and stool. After a period of infection, the gland may become septic and the blocked ducts prevent the flow of pus outward. At this time, the patient’s inguinal lymph nodes may also be larger than normal, the white blood cell count increases, and the body temperature tends to rise. If vestibular adenitis is not treated promptly, there is the possibility of spreading to the surrounding area, resulting in the formation of a perirectal abscess, and in severe cases, the rectum can be ulcerated. The actual vestibular adenitis is a more harmful inflammation, you should pay attention to vulva cleanliness and keep good sexual habits to minimize the possibility of vestibular adenitis.
