You may have more than one type of nasal inflammation. For instance, you could have nasal allergies complicated by a nonallergic nasal inflammation, nasal polyps, or a nose deformity such as a deviated septum. Only your doctor can accurately diagnose whether allergies or something else is causing your nasal symptoms. However, the chart below can help:
|Seasonal||Pollen, some molds||Runny nose, congestion, sneezing, watery, itchy eyes, postnasal drip||Seasonal (spring, summer, fall, winter) in most climates|
|Perennial (year-round)||Dust mites, cockroaches, pet dander, mold spores||Runny nose, congestion, sneezing. postnasal drip, watery, itchy eyes||All year as long as allergens are present|
|Irritant (vasomotor)||Fumes, perfumes, cleaning products, cigarette smoke, weather, stress, some types of medications, sometimes unknown||Runny nose, congestion, less sneezing and itching||All year whenever irritants are present|
|Eosinophilic||Blood cell reaction, changes in the environment||Runny nose, congestion, less sneezing and itching||As long as substance causing symptoms present|
|Neutrophilic||Blood cell reaction, sinus infections, other infections||Runny nose, congestion, less sneezing and itching||As long as infection present|
|Structural||Deformity, damage to nose||Runny nose, congestion, less sneezing and itching||As long as deformity or injury present|
|Hormonal||Pregnancy or hypothyroidism||Runny nose and more congestion than other forms of nasal inflammation||Second month to term for pregnancy-related, or until thyroid condition is treated|
|Infectious (cold/flu)||Cold/flu viruses||Runny nose, congestion, less sneezing and itching, fever, muscle aches||7 to 10 days|
