If a woman has a wet feeling down there all the time, the most common clinical cause is due to vaginal inflammation. If there is no history of sexual intercourse, the lack of diligent changing of sanitary napkins during menstruation and the lack of strengthening of vulvar care in daily life may also lead to local inflammation of the vagina, resulting in increased discharge, often accompanied by an uncomfortable feeling of vulva, or a burning sensation in the vulva, or accompanied by vulvar itching. It is advisable to go to the hospital to take the discharge for laboratory tests to find out the pathogenic bacteria infected and then give the appropriate treatment according to the results. It is recommended that women should keep their vulva clean in daily life, strengthen local care, wash their vulva once a day, and change sanitary napkins regularly, especially when they have their menstruation. It is also recommended to use cotton sanitary napkins to ensure good local ventilation and reduce local inflammation.
