Pain around the navel can be caused by infection or cold in the navel or inflammation of the mesenteric lymph nodes. The precursor of cancer is usually an unexplained lump with a tendency to increase gradually, accompanied by weight loss, fatigue, local pain and other symptoms. The navel is a tissue of the body, which is a blind tube formed by the gradual atrophy of the umbilical cord after ligation, and basically has no physiological function. As the navel opens outward, there is no peristaltic movement, and some foreign bodies can easily cause decay and deterioration after entering, and serious belly button infection can occur. Therefore, if there is a vague pain next to the navel, it is recommended that the patient go to the hospital for a comprehensive abdominal examination to clarify the type of disease and then take targeted treatment. In addition, patients are advised to keep their abdomen warm and not to catch a cold, and to avoid cold, spicy and stimulating foods in their diet and to maintain good rest.
