Chronic throat itching is usually caused by the presence of chronic irritants or chronic diseases, such as long-term heavy smoking, air pollution, dust and other irritants. Chronic diseases such as chronic rhinitis, sinusitis, chronic pharyngitis, chronic laryngitis and other inflammatory conditions exist for a long time, so the patient may subjectively feel that the throat is itchy for a long time.
In this case, the cause should be identified in time to avoid delaying the diagnosis and treatment of the disease. It may also be a throat manifestation of allergic cough or variant asthma.
