If there is yellow vaginal fluid, no lower abdominal pain and no lumbosacral pain, the most common cause is due to local inflammation of the vagina and it is important to carefully observe whether the yellow fluid irritates causing vulvar itching and whether there is a bad odor. In clinical practice, diazotide suppositories can be used. Diazotide suppositories can treat not only bacterial vaginosis, but also Candida infection, trichomonas vaginitis, and also miscellaneous bacterial infections, so this drug can be used to give treatment. In addition, it is also recommended to take appropriate tests in time. If the symptoms of yellow vaginal discharge do not decrease after taking the medication, but get worse, stop the medication in time and go to the hospital to take appropriate tests to rule out other diseases.
