Nasal acid is stimulated by cold air when there is rhinitis, and nasal mucosa contraction causes nasal mucosa spasm, which leads to nasal acid. Another situation is that it is easy to have a sore nose when you have a cold. When this symptom occurs, you should try to wear a mask when going out to prevent the stimulation of cold air. Pay attention to it in the house at ordinary times. Don't be too dry, try to keep the humidity indoors. If it is too dry, it will easily irritate the nasal mucosa and aggravate the symptoms of nasal acid.

In addition to nasal symptoms such as sour nose, sneezing and tears, cold patients are often accompanied by systemic symptoms such as fatigue, fever and headache, and may also be accompanied by symptoms such as cough and sore throat. Nasal examination showed congestion and swelling of nasal mucosa, showing acute rhinitis. Blood routine examination may have abnormal white blood cell count or classification, and may have abnormal neutrophils, lymphocytes or monocytes. Except for severe cases, most cold symptoms will relieve themselves for about a week. Most cold patients just need to drink more water and pay attention to rest to heal themselves.
