The examination for intercostal neuralgia includes two parts. The first part is to confirm whether it is indeed intercostal neuralgia, often based on three reasons. The first is pain that follows a semicircular path along the ribs. Second, there are usually fixed tender points or percussion points, also called trigger points, where pressing will cause pain and lead to a type of pain that radiates along the path of the intercostal nerves. The third is that it is more commonly seen between the fifth and ninth ribs, often causing pain or triggering increased pain during activities like sneezing or deep breathing. With this, it is basically possible to diagnose intercostal neuralgia. However, identifying the cause of intercostal neuralgia is very complex. The usual causes of intercostal neuralgia include five aspects: The first is congenital anomalies, the second is trauma, the third is tumors, the fourth is inflammation, and the fifth is other causes. Therefore, a complete diagnosis of intercostal neuralgia should not only confirm the presence of intercostal neuralgia but also identify the underlying cause. Only by treating the cause of the intercostal neuralgia can there be a very good treatment outcome.
