If a woman has trichomoniasis or bacterial vaginosis and has a history of sexual intercourse, she can be treated with metronidazole vaginally. There are two possibilities for the discharge of secretions after using the medication. The residual residue will also be discharged from the vaginal opening mixed with leucorrhea, so it is not only the discharge but also the curd-like residue, which is the normal performance of the medication and does not need any treatment, but continue the vaginal medication. However, if there is a burning sensation or redness at the site of the medication, you should stop using the medication, probably due to allergies, and go to the hospital if necessary.
