Respiratory tract edema is a relatively severe medical condition, and its main symptoms can be summarized as follows:

1. Difficulty breathing: Due to edema compressing the airway, patients may experience obstructed respiration, resulting in symptoms such as shortness of breath and wheezing.

2. Cough with sputum production: Patients may experience frequent coughing and produce sputum. In severe cases, the sputum may appear pink and frothy, which is a characteristic manifestation of respiratory tract edema.

3. Nasal congestion and runny nose: Respiratory tract edema can also cause nasal blockage, impairing nasal airflow, and may be accompanied by nasal symptoms such as rhinorrhea.

4. Sore throat: The edema may cause pain in the throat area, which can worsen during swallowing.

5. Other symptoms: Depending on the severity and underlying cause of the edema, patients may also experience symptoms such as fever, chills, hoarseness, and stridor. In severe cases, life-threatening conditions such as suffocation may occur.

As symptoms of respiratory tract edema are diverse and can deteriorate rapidly, immediate medical attention should be sought upon the onset of related symptoms to ensure timely and effective treatment.
