Soft tissue contusion of the right chest wall and rib fracture caused by chest trauma, such patients generally have a clear history of recent chest trauma, with obvious local tenderness on physical examination, or even a bone rubbing sensation, and the diagnosis of rib fracture can be clarified by chest imaging. Second, right thoracic intercostal neuralgia, patients generally have a recent history of obvious overexertion, mental stress, irregular life and other factors.
