My daughter has been coughing more, especially in the morning. She will get to coughing so much that she throws up mucus and thick spit. It only seems to happen when her sinuses are acting up and she has constant drainage. I know it is good for them to cough up everything but what I am wanting to know is this a bad sign of a lung infection or what? She does breathing tx's 2x a day along w/CPT's using Albuterol and Pulmicort. I'm so tired of all this medications I have her on and nothing seems to work. Zyrtec, Rhinocort, Singular, the two mentioned above, and of course another antibotic as always. I hear of people who have alot of coughing, why is that? Is it due to bad sinuses and drainage or something else? Should I give her a cough medicine or what when she starts to drain or let the antibotic take its course? I know I have heard not to give cough medicine but my daughter's CF clinic tells me to give her cough medicine at times. So which is it. Sorry for so many questions.Thanks.mother of 2 yr old w/CF
