Acute upper respiratory infection, commonly known as a cold, is usually just the common cold. Patients typically display various degrees of fever, along with nasal congestion, runny nose, sneezing, sore throat, and coughing as clinical symptoms. Therefore, when a patient has an upper respiratory infection and exhibits fever, they may experience varying levels of headache, dizziness, and general weakness. In such cases, upper respiratory infections are generally caused by viruses. Thus, it is necessary to administer antiviral and detoxifying medications, and if the patient has a high fever, antipyretics should be used. Once the body temperature returns to normal, it usually stabilizes quickly, and the headache caused by the upper respiratory infection will naturally subside. (Please take medication under the guidance of a physician.)
