What should you know about constant hay fever?

Hay fever is allergic rhinitis: the nose reacts to airborne allergens and becomes inflamed. Sneezing, an itchy or blocked nose, watery eyes, post-nasal drip, and reduced smell may continue when exposure is ongoing. Allergic conjunctivitis can explain prominent eye symptoms, while sinusitis or chronic sinusitis may cause facial pressure and thick nasal discharge. Hay fever can also coexist with asthma, where wheeze or chest tightness matters.

Symptoms that occur indoors, outdoors, or after contact with dust, pets, or other triggers can help identify a pattern. A blocked nose at night may disturb sleep and worsen daytime tiredness.

Arrange review when symptoms persist, disturb sleep, impair concentration, or do not respond to your usual plan. Limit known triggers where practical, rinse the face after outdoor exposure, and keep living spaces clean without creating dusty air. Ask a pharmacist or clinician about suitable nasal treatments and how to use a spray correctly; some products work through regular use rather than immediate relief. Avoid using decongestant sprays for longer than advised.

Seek urgent help for difficulty breathing, wheezing that is worsening, swelling of the lips or tongue, or sudden severe allergic symptoms. Arrange medical review for persistent fever, one-sided facial swelling, severe facial pain, recurrent nosebleeds, or symptoms that are steadily worsening. Night-time breathing pauses or loud snoring with marked daytime sleepiness also merit assessment.

Ask which symptoms suggest allergic rhinitis rather than sinusitis, whether asthma or eye involvement should be checked, which treatment is suitable, and how to manage symptoms during likely exposure periods.
