Spring is a difficult season for people with sensitive bodies. Spring is windy, with a lot of floating dust in the air, flying with willow flakes, pollen and other allergy-prone factors, which can easily lead to allergic diseases, such as allergic rhinitis. Allergic rhinitis is a disease characterized by sudden and recurrent episodes of nasal itching, sneezing, runny nose and nasal congestion, which is very similar to cold symptoms, and how to identify these two diseases, mainly in the following aspects. 1, medical history: Some patients with allergic rhinitis can provide a family history, that is, the patient’s relatives have suffered from allergic diseases such as allergic rhinitis, allergic asthma, urticaria, hygroma or drug allergy. Or the patient himself has a previous history of suffering from similar allergic diseases. And most of the cold patients have a history of cold. 2. Symptoms: Although both have itchy nose, sneezing, runny nose and nasal congestion. But the itchiness of allergic rhinitis is heavier than that of a cold, and the number of sneezes is much higher in allergic rhinitis than in a cold, usually 1-2 in a cold, but at least 3 or more in allergic rhinitis, and some patients have to sneeze a dozen or even more. The runny nose is also different, allergic rhinitis is a lot of clear water-like nasal mucus, while the nasal mucus of a cold is clear at first, but slowly becomes sticky, there is a conversion process. 3, signs: the performance of the nasal mucosa allergic rhinitis is mainly pale or gray, while the cold is mainly congested. 4, examination: you can do allergen testing, allergic rhinitis generally have a positive finding, while cold patients are not, unless the patient itself has allergic diseases. This is the general difference between the two. If you still can’t identify them, you can go to the hospital and do the allergen test so that the doctor can help analyze them.
