Dry nostril pain is an acute inflammatory disease of the mucous membrane of the nasal cavity, which is more frequent in autumn, winter and spring. Rhinovirus infections are common. Bacterial infections are often secondary, such as streptococcus, Streptococcus pneumoniae, Haemophilus influenzae, etc. It often develops when the resistance of the whole body or the defense function of the nasal mucosa decreases due to cold, humidity, excessive fatigue, excessive smoking and alcohol, etc. The virus takes advantage of the situation and invades. The presence of lesions in the respiratory tract, such as tonsillitis and sinusitis, also tend to induce dry nostril pain.
According to the clinical manifestations, the diagnosis of dry nostril pain is divided into three phases: (a) initial phase (prodromal phase): about 1~2 days, mostly manifested as generalized generalized acidity and sleepiness, dryness and burning in the nose and nasopharynx, dry nostril pain, congestion and dryness of nasal mucosa; (b) acute phase (wet phase): about 2-7 days, gradually with nasal congestion, increased nasal discharge, sneezing and itching in the nasal cavity, occlusive nasal sound in speech and decreased sense of smell. The nasal mucosa is obviously congested and swollen, and the nasal cavity is filled with mucous or mucopurulent secretions, which may turn into pus-like. The whole body has different degrees of fever, head swelling, headache, etc.; (iii) Terminal (recovery period): nasal congestion is gradually reduced and pus discharge is also reduced, and if no complications occur, it can heal itself after several days. Complication inflammation may also spread downward and inflammation of the throat, trachea and lungs may occur.
