However, some researchers argue that the flow of mucus down the back of the throat from the nasal cavity is a normal physiologic process that occurs in all healthy individuals. [1] Some researchers challenge post-nasal drip as a syndrome and instead view it as a symptom, also taking into account variation across different societies.
Nasal itching and paroxysmal sneezing are usually associated with nonallergic rhinitis rather than allergic rhinitis. [ 4 ] [ 5 ] Other symptoms that are more specific to non-allergic rhinitis include ear plugging or discomfort with eustachian tube dysfunction , headaches, sinus pressure, and muffled hearing.
Common symptoms are a stuffy nose, runny nose, sneezing, and post-nasal drip. [4] The inflammation is caused by viruses, bacteria, irritants or allergens. The most common kind of rhinitis is allergic rhinitis, [5] which is usually triggered by airborne allergens such as pollen and dander. [6]
Nasal polyps are noncancerous growths within the nose or sinuses. [1] Symptoms include trouble breathing through the nose, loss of smell, decreased taste, post nasal drip, and a runny nose. [1] The growths are sac-like, movable, and nontender, though face pain may occasionally occur. [1] They typically occur in both nostrils in those who are ...

Ultimately fluid or blood will fill the space. In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region.
One of the purposes of nasal mucus is to warm inhaled air to body temperature as it enters the body; this requires the nasal cavities to be constantly coated with liquid mucus. In cold weather the mucus lining nasal passages tends to dry out, so that mucous membranes must work harder, producing more mucus to keep the cavity lined.
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
