An itchy nose, itchy eyes and sneezing are among the signs of allergy. This is most likely due to allergies.
Allergic diseases are local manifestations of systemic diseases and manifest as different diseases in different areas. When the nasal cavity is repeatedly inhaled with allergens such as dust mites, pollen and irritant gases, the irritation of the nasal mucosa causes sensitisation and excitation reactions, causing the release of inflammatory mediators such as histamine and leukotrienes, resulting in symptoms such as itchy nose, sneezing and itchy eyes, and even rashes and redness on the skin.
