Pollen allergies aren't usually characterized by a sore throat, and headaches are among the less common symptoms of a pollen allergy. The more typical symptoms of a pollen allergy -- also called allergic rhinitis or hay fever -- are a runny nose, sneezing, itchy or water eyes, nasal congestion and an itchy throat.
The reason symptoms mainly affect the eyes and nose is because that's where pollen lands and irritates your immune system. Once your immune system detects the little pollen dust in your body, it overreacts. It misidentifies the pollen as dangerous and sends out an antibody called immunoglobulin E to fight it off.
