Allergic Rhinitis (Hay Fever)
It is believed that allergic rhinitis – either seasonal or year round – affects a very large portion of the population. Allergy sufferers can have many symptoms including runny nose, congestion, sneezing fits, itchy/watery eyes, and nasal itching. Common causes of allergic rhinitis or hay fever include pollen, animal dander, dust mites, cockroaches, and molds. Allergy skin testing can help to identify the causative agents that are responsible.

Perennial Non-allergic Rhinitis (PNAR)
More than 40% of patients with rhinitis do not have allergy at all. Perennial non-allergic rhinitis or PNAR is more common in adults, and can cause year round symptoms. PNAR sufferers tend to have more post-nasal drainage, and nasal congestion. But, the symptoms can mimic or mirror allergic rhinitis. In these cases, allergy skin testing is negative.
Nasal Congestion
Many different things can lead to nasal congestion. In addition to allergic rhinitis and PNAR, septal deviation or some degree of nasal deformity, nasal polyps, acute or chronic sinusitis, migraines, cold temperatures, common cold, medication side effects, large adenoids, foreign body, pregnancy, or chemical or irritant exposures at home or work can all lead to congestion.
