There are many reasons why the inside of the nose is so itchy, including allergic rhinitis, vasomotor rhinitis, nasal infections and so on.
1. Allergic rhinitis: itchy nose is most common in allergic rhinitis. Allergic rhinitis is mainly related to the environment, constitution and other factors, mainly manifested as sneezing, itchy nose, nasal congestion and other symptoms. When allergic patients are exposed to allergens, eosinophils and mast cells will secrete inflammatory mediators, which stimulate the nasal mucosa and cause the above symptoms.
2. Vasomotor rhinitis: mainly caused by physical and chemical factors, mental factors and other stimuli, manifested as nasal congestion, itchy nose, runny nose, sneezing and so on.
3. Nasal infections: such as nasal boils and nasal vestibulitis, which are mainly caused by bacterial infections and can be characterized by localized pain and nasal itching.
The above symptoms may also have other causes such as nasal polyps, etc. If the above symptoms do not get better, it is recommended to go to the hospital in a timely manner to clarify the cause of the disease and give targeted treatment.
