Dull pain under the left rib cage can be caused by multiple maladies, including a peptic ulcer, splenic infarct or hemorrhage, and trauma to the area, according to Right Diagnosis. Persistent pain in this part of the body should be evaluated by a doctor to determine the specific cause.

Peptic ulcers are inflammations of the stomach lining caused by stress, smoking or infection, states Right Diagnosis. A splenic infarct is an interruption of blood supply to the spleen, while a splenic hemorrhage is a complete rupture of the organ. Trauma refers to any severe injury, in this case to the upper abdomen.

Various gastrointestinal disorders, such as diverticulitis and irritable-bowel syndrome, can also cause temporary pain under the rib cage, according to PrimeHealthChannel.
