​Allergic rhinitis is the chronic inflammation of nasal passage that happens after being exposed to an allergen(s) and it causes many annoying symptoms. 

Children usually are unaware of the symptoms and parents often do not consider it as allergic rhinitis. Thus, a child may suffer without receiving adequate therapy.

The symptoms could be mild (not interfering with a patient’s daily activities), moderate or severe (affecting the patient’s quality of the life).

The symptoms are:
  • A runny nose with stuffiness
  • Excessive tearing or itchy eyes
  • Sneezing
  • Itchy nose or throat
  • Feeling pressure behind the nose or on either side of it (where the sinuses are)
  • Swollen and dark skin under the eyes (called ‘allergic shiners’)
Allergic rhinitis occurs according to allergen exposure. Sometimes the symptoms can come and go with seasons - seasonal allergic rhinitis - and sometimes they can last for the whole year - perennial allergic rhinitis.
