Causes of catarrh and sneezing

A Common Cold often brings blocked or runny nose, sore throat, cough, and changing mucus. Allergic Rhinitis can cause repeated sneezing, clear watery discharge, an itchy nose, and itchy or watery eyes, often after exposure to pollen, dust, or animals. House Dust Mite Allergy may be worse indoors or on waking, while Pet Allergy can flare around a cat or dog. Non-allergic irritation from smoke, strong scents, dry air, or temperature changes can also produce symptoms. Catarrh describes excess or thick mucus in the nose or throat; it is a symptom rather than a diagnosis.

Drink fluids, use a saline nasal rinse or spray, and avoid smoke and strong fragrances. Wash hands and avoid sharing towels or utensils when a cold is possible. For suspected allergy, reduce exposure to the trigger and ask a pharmacist whether Allergy Medication is suitable for you. Keep windows and bedding clean if indoor dust is a trigger, and wash hands after contact with pets. Follow product instructions and check before using medicines in pregnancy or for a child.

Arrange medical advice if symptoms last beyond the expected course of a cold, keep returning, disturb sleep, or interfere with work or breathing. Seek urgent help for swelling of the lips or tongue, wheezing, severe breathing difficulty, confusion, or a rapidly spreading rash. A high fever, severe facial pain, or one-sided foul-smelling discharge also warrants prompt review.

Do my symptoms fit an allergy or infection? Which trigger should I avoid? Is a nasal spray or Allergy Medication suitable with my other medicines or health conditions?
