Itchy nose sneezing may be related to allergic rhinitis, vasomotor rhinitis and eosinophilic non-allergic rhinitis.
1. Allergic rhinitis: after exposure to allergens in atopic individuals, IgE-mediated inflammatory mediator release, immunoreactive cells and cytokines are involved in chronic inflammatory reaction diseases of the nasal mucosa, with itchy nose, sneezing, runny nose and nasal congestion as the main features.
2. Vasomotor rhinitis: mainly caused by autonomic dysfunction, nasal nerve sensitivity to stimulus factors increases, in external factors, such as mental tension, anxiety, sudden changes in ambient temperature, endocrine dysfunction and other stimuli, can appear nose itching sneezing and other symptoms.
3. Eosinophilic non-allergic rhinitis: the etiology is unknown and the mechanism is complex. It is characterized by increased eosinophils in the nasal mucosa, which may show similar symptoms with allergic rhinitis, such as itchy nose and sneezing.
