Hello I have just joined the site today 27/07/2017. I am suffering with a crackling sound when breathing and have been ill wheezing now for almost three months non stop, day and night. I have never had anything like this before. I had a chest xray which came back ok, now am waiting to see the nurse for some sort of tests. I want to know what i've got. I've never smoked, but have a constant cough too. Any suggestions out there, its really worrying and its getting me down.
