I have a 4 1/2 month old son. He has been a congested "snorty" baby since birth. He was also very fussy. After a few go arounds with the pediatrician they decided that he had reflux so we started him on prevacid but it never really helped. He's also had a really hard time with feedings so we started seeing a speech pathologist, that said he has been gaining weight well and has stayed on the same growth curve since birth. The GI Dr. felt it was more of an "airway" issue so we saw an ENT Dr. The ENT Dr. felt that the irritation on the baby's vocal cords was consistent with reflux. So we just let it go. Then in Feb, he got bronchiolitis and was hospitalized. It took 6 days for him to improve and be released. While in the hospital they found a "shadow" on his lungs on his chest x-ray. Our pediatrician felt it was his thymus gland but the radiologist wanted it checked out because he didn't feel that it was consistent with thymus. So we were referred to a pulmonologist. After our first visit with the pulmonologist we were encouraged. He thought our son looked great and thought his lungs sounded clear so he said he was comfortable waiting and repeating the chest x-ray in 2 weeks. So we waited. Then my son got RSV and was re-admitted to the hospital. They x-rayed his lungs again and the shadow had improved but was still there. They said that it was still in the same spot or pocket. While we were in the hospital the pulmonologist visited us and said he wanted us to do the sweat test to test for Cystic Fibrosis. We were both shocked and confused. I tested negative for the gene during my prenatal screening and my son tested negative when he was screened when he was first born. That said, he has continually had respiratory issues. We're terrified and don't know what to think. Does this sound like CF? What do we do? What if he has it? What is his life going to be like?
