Overview

Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels. It is also known as nasal blockage, nasal obstruction, blocked nose, runny nose, and stuffy nose.

Pathophysiology

Many people think that a nose gets congested (stuffy) from too much thick mucus. However, in most cases, the nose becomes congested when the tissues lining it become swollen. The swelling is due to inflamed blood vessels.

Diagnosis

X ray

X-rays of the sinuses and chest x-ray

CT

CT scan of sinuses are required in some patients to make the diagnosis.
