| Seasonal Allergies: Autumn |
Itching, Puffy, Watery Eyes
Most of us associate hay fever or season allergies with spring and summer, but for some allergy sufferers, the end of summer signals the start of their seasonal allergies. Unfortunately, just because the lush growth of summer is dying back and turning the green landscape into a fall foliage spectacular is not an indication of the absence of allergens.
