If left untreated, trichomoniasis can cause pelvic inflammatory disease and pelvic infection can cause back pain. Trichomoniasis is a sexually transmitted disease that is mainly transmitted through sexual intercourse. The main symptoms are increased vaginal discharge and vulvar itching. In severe cases, when gynecological examination is performed, vaginal mucous membrane flushing, scattered bleeding spots, and even bleeding spots on the cervix forming a strawberry-like cervix are visible, and effective treatment should be given in time. Otherwise, it causes upstream infection of inflammation, resulting in endometritis, pelvic inflammatory disease causing abdominal pain as well as lumbosacral pain and other uncomfortable symptoms in women. You can choose systemic medication, give metronidazole tablets orally, or give metronidazole suppositories vaginally, and prohibit conjugal life during treatment.
