Sternoclavicular osteitis will have symptoms such as localized pain, impaired upper limb movement, elevated skin temperature, and localized abnormal bumps. Sternoclavicular osteitis is mostly aseptic or infectious inflammation of sternoclavicular bone caused by exertion, bumping, immune abnormality, trauma, etc. When patients suffer from sternoclavicular osteitis, patients will have the following symptoms: 1. Local pain: no matter it is bacterial or aseptic sternoclavicular osteitis, the inflammation may stimulate the local normal tissues and cause local pain, and the more serious the sternoclavicular osteitis is, the more obvious the local pain is. 2. Upper limb activity disorder: because upper limb activity needs the participation of clavicle, when the patient suffers from sternoclavicular osteoarthritis, it will cause clavicle activity disorder, so the patient with sternoclavicular osteoarthritis will have the symptom of upper limb activity disorder. 3. Elevated skin temperature: If sternoclavicular osteitis is caused by infectious factors, the patient will also have the symptom of elevated skin temperature in the localized area, and “redness, swelling, heat and pain” will appear. 4. Abnormal localized bumps: Sternoclavicular osteitis can cause localized soft tissue hyperplasia, and with the continuation of soft tissue hyperplasia, the patient’s sternoclavicular inflammation area may appear localized bumps. When symptoms occur and consider the possibility of sternoclavicular osteitis, it is recommended to consult a doctor in time, under the guidance of the doctor for examination and treatment.
