For example, the intestinal peristalsis increases, and the intestinal peristalsis pattern is not normal, resulting in a burst of pain in the abdomen. The location of the pain is around the belly button, or possibly in the lower abdomen, and can be relieved on its own after a period of rest, or after massaging the abdomen with the hands. If the pain is still not relieved and gets progressively worse, there may be a lesion in the abdominal cavity.
