Nasal congestion is the blockage of the nasal passages usually due to membranes lining the nose becoming swollen from inflamed blood vessels. Nasal congestion can interfere with the ears, hearing, and speech development. Significant congestion may interfere with sleep, cause snoring, and can be associated with sleep apnea.
