Nasal conditions refer to various health issues affecting the nose and its functions. Common examples include allergic rhinitis, which causes sneezing and a runny nose due to allergens, and sinusitis, an inflammation of the sinuses that can lead to congestion and facial pain. These conditions can result from infections, allergies, or structural problems in the nasal passages. Treatment for nasal conditions often involves medications like antihistamines for allergies or decongestants for congestion relief. In some cases, nasal sprays or surgery may be necessary to address underlying issues. Maintaining good nasal hygiene can also help prevent these conditions.
