Mucus, along with cilia, form part of a great filtering process that clears the nasal passages of debris formed by air particles which include pollutants, dust and microbes. However, mucus build up in the nasal tract leads to blockage of the sinus cavities. Since the three sinuses are located behind the nose, cheekbones and eyebrows, mucus build up leads to facial swelling and pain. This is due to the pressure imbalance created of the excess fluid clogged in one cavity.
Even more problematic is the situation where this excess fluid affects the proper functioning of the inner ear. Inner ear is responsible for collecting bodily signals from all the nerves thus letting the brain know about the direction of movement viz. front, back, up or down. When the signals get mixed up, the inner ear cannot coordinate the direction of movement any longer. This is one of the reasons why people suffering from sinusitis also experience frequent nausea and dizziness. Watch video in link below

Mucus, which itself is laden with bacteria collected from the nasal passages turns dangerous when it starts stagnating due to the blockage. The warm and humid environment in fact encourages the bacteria and fungi to thrive resulting in aggravation of the infection and increased inflammation. This infection is even more harmful when the body’s immune system is relatively weak. The bacteria, fungi or viral infections further infect the mucus linings causing it to swell leading to further congestion in the already narrow nasal passages.
