What are the possible causes of a dull pain beneath the left rib cage?

Generally, mild pain below the left rib cage may be caused by exercise-related injuries, gastrointestinal discomfort, pleurisy, pancreatitis, myocardial ischemia, or other reasons. It is recommended to seek timely medical attention to determine the underlying cause and receive appropriate treatment under the guidance of a qualified physician. Detailed explanations are as follows:

1. Exercise-related injuries

During physical activity, excessive pressure on the left intercostal muscles or improper movements may cause ligament damage, resulting in mild pain below the left rib cage. Swelling and tenderness may also accompany the pain. Rest is recommended to alleviate symptoms, and prompt medical consultation is necessary if symptoms are severe.

2. Gastrointestinal discomfort

If gastrointestinal discomfort exists, lying on the left side may cause gastric acid to reflux into the esophagus, triggering an inflammatory response and causing mild pain below the left rib cage. It is recommended to adjust dietary habits; surgical treatment is generally unnecessary. If symptoms are severe, medications such as omeprazole enteric-coated capsules, lansoprazole enteric-coated capsules, or intestinal inflammation relief tablets may be taken orally as directed by a physician.

3. Pleurisy

If pleurisy is present, inflammation may cause friction between the pleural layers, resulting in mild pain below the left rib cage. Active anti-tuberculosis treatment under medical guidance is recommended. Additionally, improving nutrition by consuming more meat, eggs, dairy products, fresh vegetables, and fruits, along with regular outdoor exercise, is advised.

4. Pancreatitis

Inflammation of the pancreas may release inflammatory mediators that irritate surrounding tissues and nerves, causing mild pain below the left rib cage. Symptoms may include severe abdominal pain, nausea, vomiting, and fever. Under medical supervision, medications such as amoxicillin capsules, morphine injections, or cefixime tablets may be used to manage symptoms.

5. Myocardial ischemia

The heart is located in the left chest, beneath the rib cage. Factors such as late-night activities, fatigue, and hyperlipidemia may impair blood supply to the heart, leading to myocardial ischemia and mild pain below the left rib cage. Prompt medical attention is advised, and medications such as isosorbide mononitrate dispersible tablets, aspirin tablets, or clopidogrel hydrogen sulfate tablets may be used under medical guidance.

In daily life, it is recommended to consume foods rich in high-quality protein and vitamins to support nutrition. Additionally, maintaining a positive mindset and actively pursuing treatment is advised.
