If the back pain is accompanied by discomfort in the stomach, it is most commonly caused by chronic pelvic inflammatory disease in clinical practice. When there is chronic inflammation, it will not only cause inflammatory reaction in the uterus itself and pathogenic bacterial infection, but also cause the ovaries, fallopian tubes, and uterine ligaments to be affected by inflammation, so when there is inflammation in the sacral ligaments, it will lead to pain in the lower back, and when there is inflammation in the adnexal area and the uterus itself, it will also lead to stomach pain. Anti-inflammatory treatment should be given according to the diagnosis. For patients with chronic pelvic inflammatory disease, it is recommended that while using medication, the diet must also be strengthened, because these patients not only have back pain and stomach pain, but also often experience fatigue. So strengthen nutrition and increase the body resistance so as to promote the full absorption of inflammation and to make the clinical symptoms improve as soon as possible.
