Mild something going on, air bubbles, air moving in lung??

[ck101]

I had asthma as a child and smoked in my 20's at weekends but would go through a pack a night. 22 years a non smoker. Now 52 . Other than my wife burning the odd candle to my annoyance I've had zero exposures to fumes.

Normal spirometry (My FEV1 has declined but still preserved close to where it was initially) but clear CT done 20 years ago. Still have a wheeze and persistent asthma like symptoms especially in the morning and suspect a bit of chronic bronchitis although I have very little sputum, only after I eat & a few specks first thing in the morning when I cough once or twice on rising.

No mucus plugging or mucopurulent type of thing. I did have that 20 years ago but it cleared up after a year or so.

I've been trying out Oxis (A LAMA) and saw some benefit at the start, now its hard to tell. Here's my question I do notice a bubbling sensation in my left lung, like air moving. Very disconcerting and all types of things come to mind. No phlegm or infection to report.

Anyone else ever have this? Waiting on a Pulmo appointment to get a check up anyway.
