If there is pain in the middle of the rib cage in the chest, first of all, it is necessary to clarify whether there is any trauma. Trauma may lead to localized rib fractures and sternal fractures, and active examination, including CT examination and 3D reconstruction, is needed to clarify the exact extent of the injury. If surgery is indicated, active surgical treatment should be performed. Conservative treatment should pay more attention to rest, avoid upper respiratory tract infections, keep the bowels open, use multiple chest straps to wrap up, which can effectively reduce the local pain symptoms, and take oral anti-inflammatory and analgesic drug loxoprofen sodium. If there is no trauma and pain occurs, actively correct the body posture, avoid local compression, avoid sleeping on the stomach, avoid repeatedly turning the chest, apply the anti-inflammatory and analgesic drug diclofenac sodium, and locally use flurbiprofen baboo. If the pain is still not effectively relieved, CT examination should be completed to clarify whether there is any tumor-occupying disease, which needs to be treated surgically.
