My 19 year old special needs daughter has had a cough, nausea, vomiting, no fever, for approximately 2 months. Then about 2 weeks ago she tested positive for influenza A. After that her breathing has kept getting worse and the cough keeps getting worse. She is now on inhalers. In a chest xray her dr did, it showed that the right side of her diaphragm is quite a bit larger that the left side. From what I ve read, this can be very serious. What is your opinion on a diaphragm that is larger on one side than the other?
