Hayfever - Why does a nose get blocked when you suffer from hayfever?

Question

Or a cold for that matter...

Answer 1

Hay fever is a seasonal allergy causing inflammation of the mucous membranes of the nose and eyes. Hay Fever is also called "seasonal allergic rhinitis" or "pollinosis."

Some of the symptoms of hay fever are: repeated and prolonged sneezing; a stuffy and watery nose; redness, swelling and itching of the eyes; itching of the nose, throat and mouth; and itching of the ears, or other ear problems.


Sneezing and swelling occurs because when the pollen (or other substance) enters the nose, the body produces antibodies against them. The antibodies release histamine and histamine irritates the upper respiratory passages. When the upper respiratory passages are irritated, swelling and sneezing often occurs.


Many people think that a nose gets congested (stuffy) from too much thick mucus. This is incorrect. A congested nose happens when the membranes lining the nose become swollen from inflamed blood vessels.


Congestion can be caused by many of the same things that cause a runny nose including colds, allergies, sinus infections, and the flu. Overuse of some nasal sprays or drops can also lead to congestion

Answer 2

Hay fever is a seasonal type of rhinitis, and is due to allergy to grass and tree pollens. People react to the pollen which causes a swelling of the lining of the nose. They also have a marked watery nasal discharge and sneezing. Often the normally white conjunctiva of the eyes is inflamed and red. This is one form of nasal allergy.

Answer 3

Its because the small capillaries in the nose get filled with blood thus swelling & blocking up, mucus can also form which will not help matters
Histamine is produced which causes the blood to rush to the nose, that is why we use anti-histamines (to stop this from happening)

Answer 4

Its something to do with the sinuses. I get hayfever horrensously. I use nasal spray to stop it blocking but now get peremnantly runny nose- damn you pollen!

Answer 6

Its common. Dryness increases. Apply mustard oil in the nostrils twice or thrice a day, specially at night before going to bed.

Answer 7

i think the sinuses actually swell up rather than getting really blocked with mucous, which a lot of people don't realise

Answer 8

Your sinuses swell...either from infection or from irritants like pollen, etc. Wish you well.

Answer 9

the skin inside your nose is reacting to the pollen and it swells up!
