Allergies are the result of an overactive immune system. In response to a substance like pollen or pet dander, the body’s natural defenses become over-activated to fight the “invader.”  Inflammatory reactions to allergens commonly occur in areas including the eyes, nose, and throat.

An influx of white blood cells and local release of irritating chemicals are the body’s response during an allergic reaction. Swelling in the lymph nodes in the area of the neck, jaw, and throat can sometimes occur.  However, swollen lymph glands can also be caused by viral and bacterial infections and other causes.

Like the other symptoms of seasonal allergies, swollen lymph nodes eventually go away without causing any problems. If you have lymph nodes that are persistently swollen for several weeks, see your doctor for further evaluation.
