Vaginal wetness and odor may be caused by increased secretion due to hormonal stimulation before and after menstruation, or it may be caused by gynecological inflammation, such as bacterial vaginitis, mycotic vaginitis or trichomoniasis. The type of vaginitis can be determined through routine leucorrhea examination and treated with anti-inflammatory suppositories or antifungal drugs. If you have cervicitis or pelvic inflammatory disease, you can have ultrasound and colposcopy. Take oral metronidazole and other drugs under the guidance of a doctor.
