I was trying to report that the Cystic Fibrosis page link on the Symptom Checker is not working, but it won t let me send it without an URL which I can t get back to. I am trying to get answers about extremely thick clear mucus, particularly after eating and at night, causing coughing, leading to vomiting. I have been diagnosed with narrowing of my bronchioles, caused by inflammation, probably caused by GERD. I have never smoked or been around second-hand smoke.
