For allergy sufferers, the release of tree pollen into the air in early spring heralds the beginning of a season filled with sneezing, itchy watery eyes and more uncomfortable allergy symptoms. Pollen is produced by trees as part of their reproductive process. In sensitive individuals, the presence of pollen triggers an overproduction of histamine, which in turn produces allergy symptoms. The trees to which people are most commonly allergic include oak, elm, hickory, box elder, ash and mountain cedar.
Eye Symptoms
Tree pollen allergies can make your eyes itch and water. Your eyes may look red and inflamed, and there may be some crusting of your eyelids. You may notice that you have dark circles under your eyes; these "allergic shiners" are caused by an increased flow of blood to your sinuses.
Nasal Symptoms
If you have tree allergies, your nose may be congested and running at the same time. You may frequently sneeze, and your nose may itch. Your runny nose may also cause postnasal drip. Children often develop a crease on their nose from rubbing their runny nose upward.
Throat Symptoms
Pollen allergies can give you a sore, scratchy throat. The soreness can be caused by postnasal drip, inflammation or both. You may find yourself coughing a lot, and your throat may feel itchy. You may become hoarse or develop laryngitis.
Other Symptoms
An allergic response can cause fatigue and mental dullness. You may feel as if you have a cold or are coming down with the flu. Your skin may feel flushed or itchy, or you may having a burning sensation. In some cases, allergy sufferers will shiver, feel dizzy or hyperactive, have stomach cramps or pains or even joint pains. If you have pollen allergies, foods in the related plant family can also cause allergy symptoms in a condition known as oral allergy syndrome.
