Suffered from COPD for the past 28 years and obviously I can tell over that time that things are getting worse. For the past few months now I have had a persistent cough which is productive but is not according to my pulmonary nurse an infection as he says my lungs are clear. All I know is I feel really unwell extremely tired and not myself at all. Does anybody have the same problem? If so how have you managed it and is there anything I can take to make life easier?
