allergic rhinitis
Seasonal nasal inflammation
Allergic rhinitis is inflammation of the nasal passages caused by an allergic reaction—typically to pollen, dust mites, mold, or pet dander.
Symptoms include sneezing, congestion, runny nose, and itchy eyes.
When triggered by seasonal pollen, it's commonly called hay fever: My allergic rhinitis flares up every spring.
