Q. How to confirm pneumonia?

Hello doctor,

My daughter is suffering from cough for the past four weeks. She started it out very gently and it is getting worse. Last weekend she was coughing almost non-stop. I took her to a Walk-in clinic and they gave her a cough syrup and an antibiotic. I was told to start the antibiotic four days later if she does not get better. I have started the antibiotics after six days. But, she was getting weaker and coughing with choking. I took her back to the doctor. They told me that she might have whooping cough. I was not entirely surprised as she had hypoxia at birth and she did not get that one vaccine: the pertussis. She only got DT. From chest x-ray, we came to know that she had pneumonia too. But, not on both lungs and the x-ray was not entirely white, so it was a smaller pneumonia. By that time we were on day three of the antibiotics. They made a sample test from the nose for whooping cough. I was told that even if she has it the results might come back negative as she took Azithromycin. We were told to wait and see after the antibiotic. The result came back negative.

The same night her cough got so bad that she was not getting any air. She was coughing without being able to breathe. She was vomiting and a tone of white long, phlegm or mucus came out with the vomiting. It was white, sticky and lots of it. In the emergency room they turned out that she had bronchospasm. They treated her with Albuterol and steroids. She was put on Albuterol for two hours there, then we came home with an inhaler. She has been using that three to four times a day ever since then. She has been very weak. They checked her again for whooping cough and that too came back negative. She took the second dose of Prednisone three pills. She felt better and was so happy. But, the next day she did not feel that good. Today, she had more coughs and it is a second sound behind the usual cough sound. This second one is like the laryngitis cough, but not barking sound. It is just a deeper cough.

I am totally lost. I do not what to do anymore. She had a different kind of cough sounds throughout for almost a period of four weeks. Intense, barking, whooping cough like, silent, more loud and now this strange one. She is allergic on Amoxicillin, Ceftin, Bactrim and Cefalosporins. I gave her Mucinex to loosen the mucus. I would like to know what to do. Should I go and see a pulmonologist in person?
