The rib cage, also known as the thoracic cage, is one of the core and most delicate parts of the human skeletal system. 24 bony structures called ribs, costal cartilages, 12 thoracic vertebrae and the sternum, all are parts that comprise the rib cage. A part of the human respiratory system, this bony and cartilaginous structure surrounds the thoracic cavity, which contains the lungs. It is a vital part of the human body and any pain in this region can be of serious concern, as it may indicate some serious medical condition or injury.

Costochondritis is a condition wherein the cartilages connecting the ribs with the breast bone are infected and inflamed. It is caused due to a viral infection, and it causes sharp gnawing pain under the left rib cage, more so while breathing deeply.

Pneumothorax is a condition where the lung ruptures due to a tear in the lung membrane, and air leaks out and fills the cavity between the lungs and the rib cage.

Treatment: This condition needs immediate medical intervention. Usually, surgery is the only option.

Irritable Bowel Syndrome

Irritable bowel syndrome is a common cause of pain under the left rib cage. It is caused by overeating or lack of fiber-rich foods, and sufficient water in the diet. In this condition, the digestive organs are affected as they are not able to secrete digestive enzymes that help in the breaking down of food into simple substances. It disrupts the normal bowel movement by causing constipation or diarrhea. Other symptoms of this condition are bloating and cramps in the intestine.

Treatment: Proper high-fiber diet along with use of laxatives is recommended for treating this syndrome.

Stomach Ulcers

Pain in left side of the rib cage might also be an indicator of the presence of stomach ulcer. Depending on the severity of the condition, the discomfort may last longer or many subside in a few minutes.

Treatment: Antibiotics prescribed by a physician can heal the ulcer and help to get relieved of the symptoms.

Constipation and Indigestion

Constipation is characterized by hardening of stools. As a result, more pressure and effort needs to be put in, to pass stools. It leads to irritating pain in the stomach, more so under the rib cage. Indigestion is also another common reason for the pain. A pain that starts suddenly can be linked to indigestion. It is usually preceded by constant burping.

Treatment: Taking antacids and other drugs to reduce stomach acid can be of help. Avoiding hot and spicy food is a must.


Diverticulitis is characterized by small, bulging sacs or pouches of the inner lining of the intestine (diverticulosis) that become infected. It generally affects elderly people, about the age of 60. People suffering from it experience bloating, constipation and pain under the lower rib cage.
