Intercostal neuritis is often caused by viral infection or mechanical injury and can be a burning or stabbing pain along the intercostal nerve. Non-specific costal chondritis is also a common disease that occurs in young women and can cause pain in the chest, often in the junction of the sternum and costal cartilage. The pain is paroxysmal and tends to recur. When this happens, it is important to take rest and avoid straining and strenuous activities. In addition, oral anti-inflammatory and pain-relieving drugs can be taken to relieve the pain. If the symptoms are still not relieved or are accompanied by other symptoms, it is necessary to go to the hospital for further examination to clarify the diagnosis and to provide targeted treatment according to the cause.
