2010 is turning out to be an especially difficult allergy season since winter lasted so long and now everything is blooming at once.
Although the southeast part of the country has the highest pollen count, it isn't a breeze for Chicagoans.
If you don't treat your allergies, you're likely to get sick.
"One of the goals that I have with my patients is keep your allergies under control, and if we've done a good job, we know that you won't end up with a sinus infection," said Dr. Mary Kay Tobin, allergist, Rush University Medical Center.
Doctors say allergy medicines are especially important for kids because the sniffles can keep them from getting enough sleep and their school work can suffer.
Allergists emphasize the importance of preventive medicine to help fight the symptoms.
