My partner has recently been in hospital with pneumonia, pleurisy, and then bronchiectasis. He already has been living with COPD, without a cough, for 10 years. He was supposed to see a chest physio in hospital but this never happened. He's now trying a flutter device, and trying coughing exercises from internet info - but often awake all night coughing, and not always able to get mucus up. Is it necessary to see a physio? Have others found the flutter works for them? any hints you can give much appreciated - we would both like to get some sleep!
