In the course of daily consultation and consultation, we can find many patients who claim to have “recurrent colds” but are finally diagnosed with chronic rhinitis, sinusitis and allergic rhinitis through systematic examination. Xiao Qing, Department of Respiratory Medicine, Zhoukou Central Hospital Many of these patients are treated as colds when they have symptoms such as nasal congestion, runny nose and sneezing. The symptoms can also improve after taking oral medication for cold, but the above symptoms will be aggravated again for a short time after getting cold or inhaling special smell. The symptoms of common cold and rhinitis can be distinguished by the following methods: 1. Symptom differentiation: the first few days of the common cold will flow clear nasal discharge, gradually turning into pus nasal discharge (initially due to congestion and expansion of the nasal mucosa blood vessels, increased glandular secretion, patients with clear water-like nasal discharge, 3 to 5 days after the exudate of the mucosa sludge on the mucosal surface, the formation of purulent mucus secretions), repeated episodes of symptoms can develop into chronic rhinitis; and Allergic rhinitis patients will flow a lot of clear nasal discharge, in addition to sneezing, nasal congestion, nasal itching, and even itchy eyes (many patients are prone to attacks when waking up in the early morning, frequent runny nose during the day, nasal congestion at night, serious cases can affect sleep); 2, the course of identification: common cold will recover in a week or so, drink more water, rest, appropriate antiviral and symptomatic treatment is more effective, while allergic rhinitis has obvious seasonality and Allergic rhinitis has obvious seasons and allergens, some of which are not good for years.
