Most sore throats and nasal congestion are caused by the common cold, and a few may also be caused by influenza. Sore throat and nasal congestion may be related to nasopharyngeal mucosal congestion and edema caused by viral infection. The common cold is mainly characterized by upper respiratory katalog symptoms, mainly nasal congestion, runny nose, cough, sore throat, and may also have fever and other discomforts. Influenza is mainly based on systemic symptoms, mainly manifested as weakness of the limbs, high fever, headache and other symptoms, but also may have nasal congestion, runny nose, sore throat and other symptoms. In addition, symptoms such as sore throat and nasal congestion can also be caused by other diseases, such as rhinitis and pharyngitis, which may be mistaken as the result of influenza. Therefore, if the symptoms are not relieved or aggravated, it is recommended to consult a doctor in time, under the guidance of the doctor for relevant examinations, to clarify the cause of the disease and then follow the doctor’s instructions for treatment.
