Nasal congestion, commonly called a stuffy nose, occurs when the blood vessels inside the nose swell from inflammation, making the nose feel clogged and breathing difficult. Nasal congestion is a very common side effect of the common cold, allergies, the flu, or a sinus infection. Nasal congestion is also a common side effect of pregnancy, and may also occur as a result of using a nasal spray for too long. Nasal congestion is not serious in adults and typically goes away when the allergies or infection subside. Decongestants and antihistamines may alleviate the symptoms of nasal congestion, but do not treat the condition that causes it.
