What Is the Cause of Pain Under Your Rib Cage?

Some causes of pain under the rib cage, such as indigestion, are not very serious, while others may require urgent treatment, such as rib fractures and liver infection, according to MedGuidance. Causes may vary depending on whether the pain is on the left or right side of the body.

Common causes of pain below the left side of the rib cage include indigestion, an irritated spleen, gas, broken ribs and stomach ulcers, states MedGuidance. Other possibilities include irritable bowel syndrome, lung collapse and costochondritis, which is an infection of the cartilage in the ribs. If the pain is on the right side, causes may include gallbladder disease, a damaged liver, Crohn's disease, liver cancer, and costochondritis.

The rib cage, also known as the thoracic cavity, houses and rests on top of many vital organs, reports MedGuidance. Pain in this area could indicate a problem with any one of these organs. Pain in or under the thoracic cavity often is due to external causes that results in bruising of tissue and organs or bone fractures. Infrequent indigestion and gas trapped in the colon are causes of rib cage pain that may resolve by the passage of time, a change in bodily position or various over-the-counter products.
