If patients experience incessant sneezing, nasal congestion and runny nose when exposed to cold air, it is likely to be caused by allergy to certain substances in the cold air. In terms of treatment, it is recommended that patients actively treat the symptoms, try to wear a mask to avoid exposure to the stimulation of cold air, and at the same time, the inside of the nasal cavity can be sprayed with mometasone furoate nasal spray to alleviate the situation where the nasal mucosa is particularly sensitive. When going out, you can also apply a layer of Tess pollen blocker on the surface of the nasal mucosa, which can effectively prevent the patient’s nasal mucosa from coming into contact with allergens and reduce the patient’s allergy symptoms. If necessary, you can consider taking oral anti-allergy drugs, such as imipramine extended-release tablets or levocetirizine hydrochloride oral solution, to actively carry out anti-allergy treatment and avoid contact with allergens, so that the patient’s allergic rhinitis will improve.
