allergies in February

Mold and dust can cause year round allergy symptoms, but even if dust and mold don't bring on the sniffles for you, trees can cause your allergies to flare at this time of year, depending on where you live. "We can see tree pollen as early as February, even in the Northeast," says Marjorie L. Slankard, MD, an associate attending physician and director of the Allergy Clinic at New York-Presbyterian/Columbia University Medical Center. In the United States, trees that commonly cause allergies include catalpa, elm, hickory, olive, pecan, sycamore, and walnut. Tree pollen can cause the same symptoms as most spring allergies — watery eyes, sneezing, and nasal congestion.
