Hi im 26 years old. I have been smoking for 11 years now. Since last year, i been having this cough off and on for 2 months sometimes every 3 months. I went to the er when my chest was bad. They diagnosed it as reactive airways disease. A week later i went to see my dr and she sent a order out for a pulmonary function test. I did that and the results came back fine, and there was nothing wrong with my lungs. The er gave me albuterol ventolin hfa. Whenever i use it, the medicine makes my chest more worse. I dnt know why, but as of now im 28 weeks pregnant, and as of right now since mothers day, i been having this whistling in my chest and i have been coughing since last week sunday, with a rumbling sound in my chest wen i inhale and exhale. I havent used my inhaler or nothing else. I still have the cough with the rumbling in my chest. I cough up mucous with it. Someone tell me what is going on...one if my friends said it sounds like a chest cold. Im still smokin also. Please help or some advice. Thanks.
