What causes a dull pain under the right rib cage?

　　Dull pain below the right rib cage may be caused by sports injuries, poor posture, cholecystitis, pleurisy, duodenal ulcers, and other conditions, and management should be based on the specific situation. It is recommended to seek medical attention at a hospital promptly and follow medical advice for treatment.

　　1. Sports injuries: Inadequate warm-up before strenuous exercise or sudden high-intensity twisting or stretching movements may strain the intercostal muscles below the right rib cage, causing dull pain. Immediately after injury, physical activity should be stopped; apply cold compresses to the affected area for 15-20 minutes, 3-4 times daily, to reduce swelling. After 24 hours, apply heat to promote blood circulation and aid recovery.

　　2. Poor posture: Prolonged slouching or hunching over a desk can keep the muscles around the right ribs in a state of tension, leading to muscle strain and dull pain below the right rib cage. Maintain proper sitting posture in daily life, adjust desk and chair height while working so that your eyes are level with the computer screen. Get up and move around every hour, perform chest-expanding exercises, stretch, and relax the muscles to relieve pain.

　　3. Cholecystitis: Obstruction of the cystic duct, bacterial infection, and other factors may lead to gallbladder inflammation. The inflammatory process can irritate surrounding nerves, causing dull pain below the right rib cage, often accompanied by nausea, vomiting, tenderness in the right upper quadrant, and increased pain after consuming greasy foods. Patients may take medications such as anti-inflammatory and bile-promoting tablets, Dan Ning tablets, or amoxicillin capsules under medical guidance to alleviate symptoms.

　　4. Pleurisy: Infection of the pleura by pathogens such as viruses or bacteria may cause inflammation, and inflammatory factors can irritate the pleura, potentially causing dull pain below the right rib cage, accompanied by chest pain, coughing, and fever. It is recommended to use medications such as aspirin enteric-coated tablets, cefixime dispersible tablets, or ibuprofen sustained-release capsules under medical guidance to relieve pain and reduce inflammation.

　　5. Duodenal ulcer: Excessive gastric acid secretion, Helicobacter pylori infection, and other factors may damage the mucosa of the duodenum, forming ulcers. During an ulcer episode, dull pain may occur below the right rib cage, often occurring during fasting periods, and may also be accompanied by acid reflux, belching, and other symptoms. Patients may follow medical advice to use medications such as omeprazole enteric-coated capsules, colloidal bismuth pectin capsules, or metronidazole tablets to improve symptoms.

　　In daily life, it is recommended to adjust dietary habits, avoid overeating and greasy foods, and increase dietary fiber intake to promote health.
