Chronic pain along the rib cage may be caused by costochondritis, intercostal neuritis, cholecystitis, and other conditions such as hepatitis. 1. Costochondritis: Costochondritis can be caused by bacterial or viral infection or cardiothoracic surgery. Long-term pain along the rib cage can occur when stimulated by inflammation. 2. Intercostal neuritis: the occurrence of intercostal neuritis is related to many factors, such as herpes virus infection, thoracic spine tuberculosis, thoracic spine degeneration, tumors and so on. As the intercostal nerves are compressed and irritated, inflammation occurs, and then the pain in the area of the strip from back to front will appear. 3. Cholecystitis: Long-term pain along the ribs may also be caused by cholecystitis, which is mainly related to cholestasis, bile duct obstruction, bacterial infection and so on. The patient may have discomfort in the right upper abdomen, which may be limited to the edge of the rib cage, or may radiate to the shoulder. 4. Others: Long-term pain along the rib cage may also be related to hepatitis, cirrhosis, liver cancer and other diseases. There are many reasons leading to long-term rib edge pain, and it is recommended that the patient actively cooperate with the doctor to improve the relevant examination, so as to avoid delaying the condition.
