An allergen such as mold spores or pollen enters the body through the mouth or nose or lands on the skin. Special white blood cells (T-cells) recognize the allergen as foreign and release chemicals in response. These chemicals travel through the blood and instruct another kind of white blood cell (B-cells) to produce IgE antibodies. Some of these antibodies attach to the outside of another special type of white blood cell called a mast cell. Mast cells are scattered throughout the skin and respiratory tract and their purpose is to help mediate the inflammatory response of the immune system. IgE antibodies can remain attached to mast cells for many years.

What causes my allergies to flare up in the spring? Pollen is the most likely cause. Your immune system has mistakenly learned to remember the pollen released by various plants as potentially harmful, and responds with the familiar allergic symptoms. Each species of plant releases pollen at about the same time every year. Trees are usually the first plants to release pollen, usually in the early spring. Grasses come next in the spring and early summer. Weeds generally release their pollen in late summer and fall. The specific types of pollen and the time of their release depends upon the local climate and varies around the country. People with seasonal rhinitis are often allergic to more than one type of pollen.

How can I tell whether I have allergies or just a cold? Generally, allergies last longer than a cold, often for a few weeks. If you notice a pattern in which you suffer the same symptoms at the same time year after year, you are likely suffering from allergies. Frequent sneezing and itchy, watery eyes are more often associated with an allergy rather than a cold. Also, a clear nasal discharge suggests that you are suffering from allergies. When you have a cold, the mucus is usually greenish or yellowish. A low-grade fever may also indicate a cold. Sometimes it can be hard to tell the difference between seasonal allergies, a cold or another condition. That's when skin tests and an evaluation by an allergist may be necessary.
