A nose that is runny or blocked, sneezing, and postnasal drip are typically caused by hay fever; however, these symptoms aren't necessarily caused by an allergy.
Hay fever can have a major impact on your daily routine, especially when symptoms are acute despite antihistamines, nasal sprays, and allergen-avoiding measures.
Allergic rhinitis is an allergy that causes nasal congestion, sneezing, itchy eyes, and a runny nose. It can be present seasonally or all year round and is a problem for millions of people throughout the UK.
