Hay fever; Nasal congestion - allergies
The general symptoms of rhinitis are congestion, runny nose, and postnasal drip, in which mucus drips into the throat from the back of the nasal passage, especially when lying on the back. Symptoms may vary depending on the cause of rhinitis. Symptoms of influenza and sinusitis must also be differentiated from allergies and colds.
Symptoms of allergic rhinitis occur in two phases, early and late.
Early Phase Symptoms. The early phase occurs within minutes of exposure to the allergens and includes:
Late-Phase Symptoms. The late phase occurs 4 - 8 hours later and may include one or more of these symptoms:
