I have been diagnosed with " scarring" and some signs of emphysema,I am 78 Lady, I have bouts of persistent cough.Sometimes hours even whole days, without it, then a run of several days with, "They" think it not serious. The Doctor does not seem concerned. But I have medical insurance so we are seeing a good specialist.He quizzed me for an hour, I smoked slightly in my youth. I have the usual puffer for emergencies, and a " triggered" dosage round thing, which I use. I am not distressed at all with breathing, it is just this persistent , not hacking, but deep, but light and persistent bouts...everyone remarks on it. I am really new into this treatment programme, more a diagnosis programme really, , and have "put up" with the cough for three years.
