My 5 year old daughter was diagnosed with asthma when she was 18 mo. old. She was a 32 wk. preemie but never had the CF screening because it was not offered. Anyway, her asthma has progressively gotten worse and worse. Since Aug 2005 she has been hospitalized for astma and phuenmonia 6 times. This last time they careflighted her to the Childrens hospital where they told me that her x-ray wasnt clear but it wasn't pheumonia. Yet her wt. blood cell count was high but she had no fever. They sent her home. She has a persistant cough that seems to never go away, and has her neb treatments at least 5 times a week during a good week. Her pulmonlogist is unwilling to do any additional testing saying that she has asthma only. She has tested negative for all allergies. And her Ig? test have all come back normal. It was suggested to me by another doctor that she have a sweat test done. Should i be worried?
