IfHayfever photo you have hayfever (rhinitis), it happens because the lining of your nose is inflamed. This causes your nose to get blocked up, run or itch as well as making you sneeze. In many cases, summer hay fever is caused by an allergy to grass pollen.

But, not all rhinitis is caused by allergies - there are quite a few cases of non-allergic rhinitis, including structural problems in the nose. This can include a deviated nasal septum, perforated septum or adenoidal hypertrophy, or inflammatory problems, such as nasal polyps. Medication taken for other conditions can also cause rhinitis.  


Rhinosinusitis is a more complex condition. It involves inflammation of the sinuses as well as to the lining of the nose, and symptoms typically include:

  • nasal blockage and congestion
  • facial pain and discomfort
  • nasal discharge, either from the front of the nose or as a post-nasal drip

Many of the causes are the same as for non-allergic rhinitis. 

Skin prick testing

Skin prick testing is a universal allergy test and often used to find out what is causing an allergy. 

Oral food challenge

Oral food challenges are tests that use suspected food allergens. The foods that we most commonly test are peanuts, tree nuts and shellfish.

Drug challenge testing

This form of testing comprises of a series of tests to see if you are allergic to certain drugs, all under close medical supervision. 

Molecular diagnosis

Molecular diagnosis covers tests which can assess whether someone has antibodies against a particular protein in a food which causes an allergic reaction.

Nose clinic tests

Patients coming to the nose clinic will have a number of tests, often including an examination using an endoscope, skin prick testing, chest peak expiratory flow and spirometry.

Nasal sprays

Corticosteroid nasal sprays or drops are the most effective standard treatment for hay fever and other nasal allergies. 


Antihistamines prevent histamine causing the itching and swelling that occurs when you have allergies.


Allergen immunotherapy is a treatment in which the allergen that triggers an allergic reaction is given in order to suppress unnecessary reactions.
