The reasons why vaginitis does not heal are as follows: 1, no detailed bacterial culture is done, so the drugs chosen are not well targeted, it is recommended to go to a regular hospital to do a detailed bacterial culture of vaginal secretions plus drug sensitivity test to choose sensitive drugs for the pathogenic bacteria, which are more targeted and have a better treatment effect; 2, during the treatment of vaginitis, if sexual intercourse occurs, it is very easy for cross infection to occur. The vaginitis treatment process should be stopped temporarily to avoid cross-infection; 3. It is important to pay attention to local hygiene during vaginitis treatment, use medication on time and avoid stopping it at will.
