Following a cruise over 6 years a go during which there was problems with the air conditioning unit in the corridor outside my room which resulted in a very wet carpet, on returning home I developed severe catarrh which I was refereed to a consultant for. Following a number of tests I was discharged as there was no apparent cause for it. I later developed a productive cough which I have had every day since. I have no breathing problems the only other symptom I have is night sweats. I have been diagnosed as having COPD but haven't actually had any tests. Could I be suffering from Aspergillosis ?
