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.
In one study, about 25% of people with rhinitis had local allergic rhinitis. [45] In several studies, over 40% of people having been diagnosed with nonallergic rhinitis were found to actually have local allergic rhinitis. [41] Steroid nasal sprays and oral antihistamines have been found to be effective for local allergic rhinitis. [42]
Rhinomanometry may be used to measure only one nostril at a time (anterior rhinomanometry) or both nostrils simultaneously (posterior rhinomanometry). In anterior rhinomanometry, the patient is asked to blow his nose, sit in an upright position, and the pressure sensing tube is placed in one nostril, while the contralateral nostril is left opened.
Rhinitis medicamentosa is a form of drug-induced nonallergic rhinitis which is associated with nasal congestion brought on by the use of certain oral medications (primarily sympathomimetic amine and 2-imidazoline derivatives) and topical decongestants (e.g., oxymetazoline, phenylephrine, xylometazoline, and naphazoline nasal sprays) that ...
Commonly reported are feelings of nasal obstruction, nasal dryness and crusting, and a sensation of being unable to breathe. [3] The overall incidence of ENS is unknown due to the small body of epidemiological study and the lack of a dedicated International Classification of Diseases (ICD-10) code, which would allow incidence reporting of the ...
As the cavity fills up, it blocks off the air passageway, causing difficulty breathing through the nose. Air caught in nasal cavities – namely the sinus cavities, cannot be released and the resulting pressure may cause a headache or facial pain. If the sinus passage remains blocked, there is a chance that sinusitis may result. [6]

Paroxysmal sneezing in morning, especially in morning while getting out of bed. Excessive rhinorrhea – watering discharge from the nose when patient bends forward.
