Mucus is a common temporary nasal obstruction. It can accumulate in the sinus cavities and lead to nasal congestion and decreased airflow. Generally, nasal obstructions caused by mucus are temporary and will go away on their own with time. However, treatment may be required for mucous blockages caused by chronic conditions.

People experience excess mucus for any number of reasons including sinusitis, allergies or rhinitis (inflamed sinuses). Mucus buildup is uncomfortable and can lead to a runny nose, post-nasal drip, and nasal inflammation. Excess mucus in the nasal passageways can cause congestion, making it difficult to breathe.


Fortunately, most causes of mucus buildup are acute and will clear up on their own without treatment. If symptoms linger, there are at-home therapies available.
