Why Does Your Nose Run? Colds, Pollen and Allergy Questions

A runny nose can occur with a respiratory infection, an allergy or irritation. The pattern and accompanying symptoms help a clinician or pharmacist decide what to assess; the symptom alone does not identify the cause. If you are searching from Nigeria, do not assume that another country’s pollen calendar or allergy statistics describe your own location.

Cold or allergy?

The NHS describes allergic rhinitis as an allergic response that can cause sneezing, itching and a runny or blocked nose, sometimes with watery eyes. Pollen, dust mites, animal dander and mould are examples of triggers. Symptoms can resemble a cold, so uncertainty should be discussed with a professional.

A cold involves an infection and irritation of the nasal lining. A repeated pattern after a particular exposure may suggest an allergy, but that observation is not a diagnosis. Record timing, duration, fever if present and whether other people around you are unwell.

Why there may seem to be more pollen

Pollen exposure varies with local plants, season and weather. A photograph of yellow dust or an overseas forecast is not a measurement of the air at your home. Ask whether a local monitoring source exists before relying on a count.

There is no single prevalence percentage that applies to every country, age group or definition of pollen allergy. A useful statistic names the population, date and measurement method. This guide does not import UK percentages into a Nigerian health claim.

Choosing a next step

A pharmacist can help with suitable options for uncomplicated symptoms and check product instructions, interactions and age restrictions. Avoid combining medicines merely because they have different brand names. Persistent, worsening or unclear symptoms deserve medical review, especially if asthma is affected.

Severe breathing difficulty, throat swelling or collapse needs urgent emergency care. Do not treat those symptoms as an ordinary runny nose. Seek a local emergency service or the nearest appropriate emergency department.

For pharmacies and institutional buyers

Consumer-health procurement should specify the actual product category, authorised supplier, destination registration, storage conditions and traceability. An educational article does not establish that a medicine is suitable for an individual. Wigmore can discuss lawful supply-chain enquiries; personal clinical questions belong with a pharmacist or clinician.
