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.
Pollens spread by the wind. Pollen from trees, grasses, and weeds are the main cause of allergies. Spring is not the only allergy season, many plants pollinate year round. Your location will determine the time and duration of your pollen season. Pollen counts will vary from day to day as well as hour to hour. Different Pollens for Each Pollen Season . In springtime, pollen from the trees begins its release between January and April, depending on the climate and location. These trees include elm, pine, birch, ash, hickory, poplar, and cypress to name a few. Summertime is when grass pollen reigns supreme: pollen from northern grass in colder climates, such as timothy, rye, and blue; and southern grass pollens in the warmer climates, such as Bermuda Grass.
