Pain in the five fingers below the navel is associated with constipation, rectal diseases, appendicitis, and genital diseases. When the pain in the five fingers below the navel is located on the left side, accompanied by symptoms such as abdominal distension and difficulty in defecation, it is mostly caused by constipation, which is caused by the irritation of the rectum during the discharge of feces. When there are diseases in the rectum, such as proctitis or rectal tumor, the rectal mucosa will be irritated, which will lead to pain in the rectal area. When the pain is located on the right side of the abdomen and is severe, accompanied by nausea, vomiting, fever and other symptoms, it is important to be alert to appendicitis. Some people have pain directly below the abdomen, accompanied by fever, abnormal leucorrhea, urinary urgency and other phenomena, which should be alert to diseases of the reproductive organs, such as prostate disease and urinary system diseases in men, and uterine, adnexal and ovarian diseases in women, which can lead to pain in the abdomen.
