An itchy nose most likely means you have an allergy to something, and there are several possibilities. The itching is caused by an overreaction of your body to the offending allergen. You might have other symptoms, including an itchy throat or eyes, sneezing and runny nose, stuffy nose, watery eyes, sinus pressure, and congestion and itching in your ears. Nonallergic rhinitis is another possible cause of an itchy nose and can be caused by a number of conditions.
