Vulvar cramping is a symptom of a heavy sensation in the vulva due to vulvar smooth muscle tumors or vaginal inflammation. The principle of treatment for vulvar smooth muscle tumor is local excision of tipped fibroids or removal of deep fibroids. The prevention of vaginal inflammation abandons the abuse of antibiotics, washing underwear separately, avoiding excessive cleaning, paying attention to nursing care in pregnancy, being wary of washing machines, and paying attention to hygiene in public places. First, discomfort in the vulvar area may be due to non-specific vaginitis, which can be detected by taking vaginal discharge for smear, mostly using Gram stain for microscopic examination. It is important to see if common pathogenic bacteria can be found in the secretions to determine the cause of vulvar cramping. Secondly, women may also have a feeling of vulvar cramping when mycosis fungoides is present. When microscopic examination of vaginal secretions is performed, clusters of Gram-positive, intensely stained spores, mostly in chains or branches, can be found, which is a more reliable way to check. Third, some women are also prone to intermittent vulvar cramping due to trichomoniasis. The examination is usually performed by taking the discharge with a small amount of warm saline that has been dripped on a glass slide. Most of the trichomonads can be seen moving. If there are special circumstances where trichomonads cannot be found, they can be examined by culture instead.
