Nasal Congestion

Sinus Congestion

Your sinuses, the pairs of cavities in your skull that connect to your nasal passageways, are thinly lined with mucus membranes to keep the inside of your nose moist. Irritants like viruses can cause the mucus membranes to become inflamed, resulting in space restriction and accumulation of mucus in the sinus. This causes that uncomfortable feeling of sinus congestion.

Sinus Pressure

Irritants can cause inflammation of the mucus membranes lining your airways and swelling of the sinus tissues, leading to space restriction and decreased drainage of the sinus. This causes excess mucus buildup, putting pressure on the underlying tissues in your face and leading to that uncomfortable feeling of sinus pressure.
