Women with pelvic inflammatory disease usually have pain all the time, not occasionally. This is because after a woman develops pelvic inflammatory disease, there are pathogenic bacteria that infect the pelvis, often causing constant pain symptoms in the lower abdomen, which may be swelling or painful downward, and there may also be anal swelling and lumbosacral soreness. If a woman has a serious pelvic infection, it may also lead to an increase in body temperature and even nausea and other uncomfortable symptoms. For women who are not menstruating, they may also have increased leukorrhea after the onset of pelvic inflammatory disease. For women who develop pelvic inflammatory disease during menstruation, it may cause increased menstrual flow and prolonged menstrual periods.
