Can anyone relate and / or explain why breathing and barking cough gets worse at night time / bed time. I was kept awake coughing for hours last night until I finally got to sleep in the wee hours.
[ Bio: I’m almost 2 months post Covid / pneumonia and a CT revealing pulmonary fibrosis. After 2 spells in hospital, first in August and most recently 2 weeks ago I was prescribed oxygen, 4L/min for mobilisation using a portable oxygen tank, and a concentrator set to 1L/min which is barely sufficient to walk around. I understand exercise is important for the body including the lungs, but I wasn’t informed what my target O2 should be when mobilised. All I know is that I get breathless really quickly on 1L.]
