Could be Rhinitis: Chronic rhinitis presents with a variety of symptoms including nasal congestion, running, ear fullness, itching (eyes and nose), and post-nasal drip that can be seasonal or year round. Triggers can be allergic (animal dander, pollen, dust mites) or non-allergic (strong scents/odors, cleaning products, weather changes). See an Allergist to determine if your symptoms are consistent with above.
