Since the symptoms of allergic rhinitis are very similar to those of cold, many parents of children with allergic rhinitis do not recognize it, thus missing the best time for treatment. In the clinic, there are many “careless” parents, when their children appear frequent sneezing, clear nasal symptoms, they think it is a cold, and give their children all kinds of cold medicine. Some children with rhinitis are neglected for a long time, triggering or aggravating sinusitis and asthma, so parents should learn to distinguish between allergic rhinitis and colds. The most typical symptoms of allergic rhinitis are: itchy nose, sneezing, runny nose and nasal congestion, some can be accompanied by itchy eyes and other eye allergies, which are often confused with colds in daily life. The onset of allergic rhinitis has obvious seasonality, mostly occurring at the time of significant temperature changes and the turn of the seasons, and often peaks whenever there is a lot of pollen in the air or cold weather. The nasal symptoms of cold such as sneezing, runny nose and nasal congestion are often persistent and will continue for several days, with the control of the cold, the symptoms gradually reduced and finally relieved; while allergic rhinitis attacks are paroxysmal and may occur once or several times a day, more obvious in the early morning or after the stimulation of odor, and after the attack as normal. Allergic rhinitis is usually not accompanied by fever, while colds are usually accompanied by fever. The following will be specific about how to correctly distinguish between the cold and allergic rhinitis: 1. First of all, the cold is accompanied by fever, with a strong contagious, so most of the group, such as family, school, work environment, etc.; allergic rhinitis is not contagious, but can be inherited, so if there are blood relatives have allergic diseases, including allergic rhinitis, asthma, skin allergies, drug allergies and other allergic history of the family, the attack The likelihood of an attack is greater. 2, people who have experienced a cold know that although the cold will sneeze, but there will not be a continuous dozen or even dozens of cases, while one of the symptoms of allergic rhinitis is continuous sneezing, some people will even be more than 30 a day. 3. When you have a cold, the main symptom of your nose is not itchiness, but prolonged nasal congestion, and nasal discharge can turn from clear snot or sticky to purulent. However, if you are suffering from allergic rhinitis, the nasal cavity and throat area will be very itchy. 4, from the symptoms accompanying the cold, runny nose usually appears at the beginning of the cold, and the flow will not be a lot, while allergic rhinitis is just the opposite, accompanied by sneezing at the same time, a large amount of nasal discharge will pour down. 5, the cold is due to viral or bacterial infection, the main reason for the onset is due to the body’s own immune system decline, so the cold when the systemic symptoms are heavy, such as cold, fever, weakness of the limbs, muscle pain, headache, sore throat, gastrointestinal discomfort, etc., while allergic rhinitis is only manifested as nasal symptoms or accompanied by asthma or skin allergies. 6, the short course of the cold, usually 1 week to heal, while allergic rhinitis is a longer course, recurring attacks throughout the year.
