”Cold” and “flu” are acute inflammatory diseases of the nasal and pharyngeal mucosa caused by viral infections. Mainly manifested as nasal congestion, runny nose, headache, sore throat, cough and other symptoms, otorhinolaryngology called acute rhinitis, acute pharyngitis, the onset of all seasons, but more common in winter. Common causes are: 1, systemic factors: such as cold, overwork, malnutrition, vitamin deficiency, excessive smoking and alcohol caused by the decline in immune function. 2, local factors: chronic inflammation of the nasal cavity, pharynx and adjacent focal diseases can impede the ventilation and drainage of the nasal cavity, affecting its physiological function, which is conducive to the local growth and reproduction of pathogens, such as nasal septal deviation, chronic rhinitis, chronic sinusitis, nasal polyps, chronic pharyngitis, chronic tonsillitis, etc.. If acute rhinitis and acute pharyngitis are not properly treated, they can evolve or the direct spread of infection can spread to neighboring organs and produce various complications: 1. Acute and chronic sinusitis caused by the spread of sinus through the sinus opening to the sinuses. 2. Acute and chronic otitis media via the eustachian tube. 3, downward spread and acute and chronic pharyngitis, acute and chronic laryngitis, bronchitis and bronchitis, children and the elderly with low resistance may be complicated by pneumonia. 4, through the nasolacrimal duct caused conjunctivitis, dacryocystitis. Therefore, how to get a “cold”, “cold”? Nowadays, small hospitals generally go to pediatrics for children and internal medicine for adults. In large hospitals, there are otorhinolaryngology departments, so you should go to the otorhinolaryngology department, because otorhinolaryngology is the treatment of “cold”, “cold”, that is, acute rhinitis, acute pharyngitis, where you can not only get the conventional cold medication, but also In this way, we can prevent the risk of complications due to delay and aggravation of the disease, and the cost of consultation and treatment in otorhinolaryngology is relatively low.
