If you have pelvic inflammatory disease, you will often feel vague pain and swelling in the lower abdomen in your daily life, accompanied by increased vaginal discharge, and the pain in the lower abdomen will increase during sexual intercourse or menstrual period. If you have these conditions, it is likely that you have pelvic inflammatory disease. It is recommended to have a gynecological examination, mainly to find out whether there is pressure pain in the uterus and adnexa. If there is pressure pain, it can be clinically diagnosed as pelvic inflammatory disease, and ultrasound examination is recommended to find out whether the pelvic inflammatory disease has formed a mass and whether there is pelvic fluid. If a mass is formed, it is recommended to treat it with broad-spectrum antibiotics combined with metronidazole for anaerobic bacteria and, if necessary, surgery.
