Under-recognized, particularly when chronic blockage (without itch/sneezing) rather than sneeze/discharge. Late phase reactions involving Eosinphil induction by T cells tends to produce chronic swelling and non-specific irritability eg cold air. Nose problems impact with everything connected eg eyes, sinuses, middle ear, lungs. Differential is wide eg CF/PCD, deviated septum, polyps.
