Cervicitis is inflammation of the cervix (lower part of the womb connecting it to the vagina), often caused by sexually transmitted infections, irritation, or an overgrowth of normal vaginal bacteria. Symptoms may include unusual discharge, bleeding, or pain during sex, though sometimes there are no symptoms. It is generally not serious if treated promptly, but if left untreated, it can lead to complications such as pelvic inflammatory disease or fertility problems. A doctor can identify the cause and recommend the appropriate treatment.
