Rhinitis is a common condition of the upper respiratory tract that is characterized by nasal obstruction and runny nose. In cases of severe inflammation, fever and headache may also occur.
Rhinitis is caused by the secretion of large amounts of purulent secretions and swelling of the mucous membrane of the nasal airways. This leads to narrowing of the passage for air to enter, which can lead to nasal congestion in mild cases and labored breathing in severe cases. The mouth needs to be opened to help breathing. Due to inflammatory irritation, radiating pain and discomfort in the area around the eyes and face can occur. In severe cases, there may be severe painful discomfort in the forehead.
Rhinitis is mostly caused by bacterial and viral infections. During the onset of the disease, symptoms such as fever, general malaise, dizziness, and weakness may occur. Body temperature is sometimes not used as the main basis for diagnosing the disease. Younger people can experience a rise in body temperature of varying degrees of height due to their better immune function, while older people may not experience significant changes in body temperature due to low immune function.
Rhinitis can also spread, and can also spread to more deeply penetrated parts of the upper respiratory tract, causing respiratory secretions. The body can develop a cough and cough up sputum in order to expel these secretions. Untreated and low resistance people lead to lower respiratory tract infections. In addition to coughing and coughing symptoms, it can also cause symptoms such as chest pain and chest tightness.
The main manifestations of this disease are mainly a series of local or systemic symptoms of the respiratory tract caused by inflammation. Timely treatment is needed to relieve or eliminate the symptoms.
