AnneRoto,
You may have a mycoplasma infection. I got one with my Lyme, and I had air trapping, got diagnosed with asthma (since most docs--esp. in the 1990s--don't test for mycoplasma), and began having extreme sensitivities to formaldehyde, chemicals, etc. over time. I was on Advent, Advair, Albuterol, Flovent. Serevent, and Prednisone at various times, esp. when the formaldehyde exposure really burnt my lungs badly. The respiratory symptoms were the first symptoms I experienced after my tick bite.
