Allergic rhinitis (hay fever) and sinus problems commonly cause symptoms such as a runny nose, sneezing, nasal blockage, itching, and headache or facial pressure. These symptoms are often triggered by dust, pollen, smoke, weather changes, or other allergens. Medicines called antihistamines, such as cetirizine, levocetirizine, loratadine, or fexofenadine, are commonly used to reduce sneezing and a runny nose. Nasal steroid sprays may also be prescribed by a doctor to reduce inflammation inside the nose and provide better long-term control. Saline nasal rinses or steam inhalation can help clear mucus and reduce congestion naturally. It is important to avoid triggers as much as possible. Keeping the house dust-free, wearing masks in dusty areas, and avoiding smoke exposure may help reduce symptoms. Drinking enough fluids and getting proper rest can also improve recovery. Do not use nasal decongestant drops continuously for many days without medical advice, as they may worsen blockage over time. If you develop fever, severe facial pain, thick yellow or green mucus, or symptoms lasting for many weeks, you should consult an ENT doctor for proper evaluation and treatment.
