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.
Pollen is a mass of fine spores containing the male cells of a plant. Trees, grasses and weeds release these particles in the air to fertilize other plants. However, many people are allergic to the chemicals they contain and weed pollen is one of the most common types that can trigger a seasonal allergy.
