Chronic pelvic abdominal pain is not usually relieved by pregnancy. Pregnancy does not cure chronic pelvic inflammatory disease and may even worsen symptoms such as abdominal pain. Chronic pelvic inflammatory disease with symptoms of abdominal pain is usually treated with antibiotics, with the main purpose of removing pathogens and improving signs and symptoms. According to the patient’s situation, follow the doctor’s instructions to choose cefotaxime, ofloxacin, metronidazole and other drugs for treatment. Moreover, in the course of pregnancy, recurrent pain in the abdomen, even accompanied by pain in the lumbosacral region, may occur due to chronic pelvic inflammatory disease. If chronic pelvic inflammatory disease shows acute attack during pregnancy, it may also affect the normal growth and development of the fetus, or even show the phenomenon of miscarriage and premature birth. Patients with chronic pelvic inflammatory disease need to consult a doctor in a timely manner and intervene in the treatment after a clear diagnosis.
