Hay Fever- Allergic Rhinitis
Hay fever is the common term for ‘allergic rhinitis’. It’s caused by an allergic response to outdoor or indoor allergens such as pollen, dust mites, fungal spores, animal fur or occupational sources.
Allergens are most commonly proteins or enzymes that can cause the nose, eyes, throat and sinuses (small air-filled cavities behind your cheekbones and forehead) to become swollen, irritated and inflamed.
