There are two main conditions to consider when the nose exhales very hot: First, there is an upper respiratory tract infection because of cold or bacterial or viral infection. Since the body temperature is relatively high, the temperature of the mucous membrane of the nasal cavity will also be relatively higher, so it feels particularly hot when exhaling. Second, the patient has inflammation within the nasal mucosa, such as the formation of boils in the nasal cavity, or the rupture and congestion of the nasal mucosa caused by picking the nose. In terms of treatment, if it is caused by an upper respiratory tract infection, the cold must be actively treated, and can be treated with Lianhua Qingfei granules or cold and fever granules, or you can also take Pudilan anti-inflammatory oral solution orally. If the nose exhalation fever is caused by inflammation, it can be treated with drops of tretinoin nasal spray, or mometasone furoate nasal spray in the nasal cavity.
