This is an infection of the womb, fallopian tubes, or ovaries that causes them to come to be inflamed and infected. Frequently, it is a sexually transmitted bacterial infection, like gonorrhea or chlamydia. These bacteria go into the uterus via the vagina as well as leave the fallopian tubes to infect bordering organs like the ovaries. Marks left by the infection may trigger persistent pelvic discomfort; nevertheless, more frequently the pain is severe.
