The most common cause of leukorrhea like yellow snot, which is not painful or itchy, is caused by localized chronic inflammation of the cervix. When there is chronic inflammation in the cervix, the cervix will become congested and edematous, and then the glands will secrete a lot, which will lead to thick leucorrhea, similar to pus nasal discharge, accompanied by pain in the lumbosacral area. You can use diazotide suppositories or metronidazole suppositories into the vagina for ten days or half a month, and take oral anti-uterine inflammatory tablets, cephalosporins or metronidazole if there is no drug allergy, for five to seven days, and take them after meals, to effectively treat cervical inflammation. Do not have sexual intercourse during the medication period, do not eat spicy and sour food, and give a review after stopping the medication.
