Well considering my symptoms would start to clear about an hour after leaving the house and return with in an hour of returning home I doubt it has been seasonal. I may have found a magic cure. I take Allegra-D in the morning, Allegra (no D) at night, and spray once a day with Nasacourt (sp?). We also found these wipes for cats. It's kinda like a BIG baby wipe, and the purpose is to give the cat a bath with out water. There is one made for shedding and allergies. That and lots of brushing seems to have made a world of difference. I still sneeze in the mornings, but none of the chest tightening, red eyes and coughing my head off.
