Frustrated

Hello,  I am frustrated.  I just bought my very first home and have been living there 2.5 weeks.  It is a 1978 home so before we moved in I had the carpets cleaned (carpet only in bedrooms and basement rest of home hardwood floors).  I also had the expensive Duct cleaning done aswell.
Sense we have lived there nothing but issues.  My daughter wakes up sneezing out a greenish flem (phlegm) from her nose and coughing.  I wake up with swallen eye lids, congestion, stuffed up ears, coughing up flem (phlegm).  She is on Zyrtek (spl?) daily.  I took her to the doc for the green nose and he said no infection that is a myth.  He suggested her Zyrtek at night instead of the morning, but it has not gotten better.  Is it something in our home causing these issues?  My room is in the basement her's is up stairs.  I don't know what else to do?  Is it just a cold or is it my new house?????  My allergyst told me once she was out of our apartment which was on the bottom level and concrete slab her allergies would get better.  They got worse for both of us.

Remove the carpets and rewash/dry clean ALL linens and draperies. Could be a virus though. The doc you visited was an allergist? If not see the allergist again. They could have had pets you are allergic to and that it is very hard to remove those allergens from the home.
