Allergy testing

Maryse has been having headaches a lot lately. So I took her to the allergy doctor. They allergy tested her for allergies to lots of different common allergens. She tested negative to everything. Good, but now what? Dr. Sandberg said that it is possible that Maryse could be "sensitive" to allergens in the air even though she's not allergic to them. So he put her on a nasal spray that she uses daily. We're hoping this will help but only time will tell.
