Seasonal Allergies: Causes and Symptoms
Don’t let seasonal allergies hold you back
Allergy season is different for everyone. That’s because different kinds of outdoor allergens - or irritants - get distributed into the air. Your seasonal allergies happen from exposure to mold spores or to the pollen that is being released by the local grass, trees and ragweed whenever that occurs in your area.
