Walking and Injuries. Any pain in the chest while walking, no matter what its cause, can be troubling -- especially if you've reached middle age, when the risk of heart disease rises. Such pain may have nothing to do with your heart, however.
The stomach, liver, spleen, gallbladder, and most of the small and large intestines are in the abdominal cavity. Many of the organs of the abdominopelvic cavity are covered by the visceral peritoneum, while the wall of the abdominal cavity is lined with the parietal peritoneum. Peritoneal fluid fills the cavity between the visceral and parietal peritoneum.
Organs of the abdomen include the stomach, small intestine, colon, liver, gallbladder, and pancreas. Occasionally, abdominal inflammation and pain may be felt in the abdomen even though it is arising from organs that are close to, but not within, the abdominal cavity.o complicate matters, however, abdominal inflammation and pain also can occur due to distention or loss of blood supply. An important example of this latter type of pain is the irritable bowel syndrome (IBS).
