Thank you for responding... The pediatrician has actually made my son an appointment with a pulmonoligist. He has had bronchitis 14 times and this is his fourth bout with pneumonia, in 3 years. I guess that his x ray has looked this way every time they have taken one, and then it gets worse when he gets pneumonia. His spirometry test was at 89 and he is scheduled for a sweat test on Jan 12th. Apparently his toenails are clubbed? I dont know, I never realized that round toenails were weird... I will try the other website. THANK YOU AGAIN !!!
