I was wondering what issues, if any, the parents who are only carriers have. As I try putting this puzzle together, I'm trying to find every single piece I can. I have asthma, which for the most part is controlled with Advair, Singulair and Albuterol, nasal polyps, sinus infections and what seems to be winter allergies that cause a lot of sinus pain, frequent upset stomach, and ear infections when I was a little one. I'm tired a lot of the time and my body aches all over, particularly my neck and shoulder area (but that could just be stress related).
