In women, a significant cramping sensation in the abdomen with lower back pain is more likely to be considered a gynecological system infection or pelvic infection. The patient may also have symptoms of urinary tract irritation, and laboratory tests may reveal elevated blood levels, and urine tests may reveal white blood cells and red blood cells. Gynecologic ultrasound should be performed in a timely manner and systematic anti-infection treatment should be administered, as many patients have exacerbation of the disease due to exertion or cold. It is also related to the special anatomical characteristics of women, so it is important to pay attention to prevention, not to strain during the acute phase of the disease, and not to bear weight, and to monitor blood changes during treatment. Many patients can gradually improve with timely anti-infection treatment, but if pelvic fluid increases or abscesses form, further surgery for drainage is required if necessary.
