Hmmm-- and on that subject, don't necessarily discount the impact of dust mite allergies as a "seasonal" allergen, either-- more time spent in indoor, carpeted, upholstered environments in the winter months can make that one SEEM like a seasonal allergy, too.
Also-- pet allergies if you yourself have a pet-free home, but classmates don't. Coats, see-- only a problem for some of the year in our part of the world.
Mold allergies can really impact quality of life a lot without you really registering that something is wrong. It is amazing what it feels like for any one of our family to go without daily antihistamine for a few days. Unreal how awful it feels.
