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.
(Flower pollen is carried by insects and does not cause hay fever.) Types of plants that cause hay fever vary from person to person and from area to area. The amount of pollen in the air can affect whether hay fever symptoms develop. 1  Hot, dry, windy days are more likely to have a lot of pollen in the air.
