When I get the flu I end up with a cough that lasts for quite some time (I m currently in my fourth week with it) and mucus build up in the airways. When I was younger I was tested for hooping cough and asthma, yet I do not have them. In 2013, I was also tested for asthma and they just said it was a lung infection. I went to the doctors last week and she said it was just a chest infection and prescribed steroids - which didn t work. So i went back to the doctors this morning and he refused to believe that chronic bronchitis is anything but impossible - I m a 20 year old female / non smoker - but my grandad has chronic bronchitis and i ve been passive smoking (unintentionally) as my mum is a smoker. is it possible that i do have chronic bronchitis?
