Upper respiratory infection symptoms generally last from three to 14 days, according to MedicineNet. Symptoms occurring for longer than two weeks may indicate an alternative diagnosis, such as bronchitis, pneumonia, allergies or sinusitis.
Common upper respiratory infection symptoms include nasal congestion, runny nose, nasal breathing, scratchy or sore throat, and painful swallowing, reports MedicineNet. Additional symptoms include cough, fever, malaise, and clear, white or green nasal discharge. Although less common, upper respiratory infections may also cause headache, shortness of breath, nausea, sinus pain, and watery or itchy eyes. Treatment for the condition depends on the symptoms, with cold and cough medications generally recommended.
