If your nose feels blocked or stuffy for weeks, and over-the-counter cold medicines aren’t helping, it could be more than just a common cold. Chronic nasal congestion is often caused by sinus infections (chronic sinusitis), allergies, or nasal polyps, noncancerous growths that can obstruct airflow. Long-term nasal blockage can lead to difficulty breathing, poor sleep, frequent headaches, reduced sense of smell, and even fatigue. Treating it like a cold won’t help if the real issue is something more persistent. If your symptoms last longer than 10 days or keep coming back, it’s time to consult an ENT (Ear, Nose, and Throat) specialist. With the right diagnosis, treatment options like nasal sprays, allergy management, or minor procedures can provide lasting relief.
