There are several factors to consider when itching outside the nose: first, the most common eczematous change of the external nose. The surface has redness, flaking of the skin, etc. You can use topical glucocorticoid ointment, such as Euthyroxel. The second type is a combination of symptoms, such as allergic rhinitis. Some patients may experience itching of the external nose, and children are often seen scratching the nose, or the nasal neck. For combined symptoms caused by allergic rhinitis, anti-allergic treatment is mainly administered locally and systemically. There are other conditions that cause itching outside the nose, such as lesions of the nose itself, such as rosacea, which can also cause itching outside the nose and need to be treated accordingly.
