There are many reasons for itchy and painful nose, including acute rhinitis, dry rhinitis, vasomotor rhinitis and so on. 1. Acute rhinitis: mainly caused by viral infection. It is characterized by sneezing, itching, dryness, burning and pain in the nasal cavity, and congestion of the nasal mucosa. 2. Dry rhinitis: mainly caused by long-term stimulation by external physical or chemical substances (such as dust), or due to over-drying and overheating of the air. It is mainly characterized by dryness, itchiness and burning pain in the nose. 3. Vasomotor rhinitis: a disease of abnormal function of nasal mucosa blood vessels and glands caused by dysregulation of autonomic nerves and endocrine regulation, which can be categorized into two types: nasal congestion and nasal overflow. The former is characterized by nasal congestion, which is mostly intermittent; the latter is characterized by increased watery nasal discharge, episodic sneezing, itching inside the nose, and pain caused by frequent rubbing. In addition to the above reasons, allergic rhinitis and other diseases can also cause the above symptoms. If the above symptoms persist, you should go to the hospital in time to clarify the cause and give targeted treatment.
