Colds with runny nose are a normal manifestation of viral infections, and usually heal as the cold recovers. Colds are usually caused by viral infections, and viruses can stimulate the nasal mucosa, resulting in congestion and edema of the nasal mucosa, and a marked increase in secretions, which is manifested as an increase in clear nasal discharge. Colds with runny noses can be treated with lifestyle modifications, such as drinking more water and resting, and are usually self-cured. After the cold is cured, the symptoms of runny nose can also be cured. If the symptoms do not go away, allergies, rhinitis and other diseases should be considered, and it is recommended to consult a doctor in time and follow the doctor’s instructions for examination and treatment.
