I'm usually replying but I thought I'd kick this off, see if anything chimes with others.
I've been diagnosed mild COPD(emps), with a few issues that make it feel worse (throat mucus, sinusitis left over from undiagnosed GERD + asthma + adverse reactions to meds).
On one of the Xrays I had left lung plate atelectasis - a minor collapse of a transverse section of lung. That's 5 years ago. But I think when I eat food that creates bloating, like sprouts, broccoli, cabbage, salads etc. I think it collapses again.. then I feel I need to clear sputum, but cant cough anything up. I get crackles if I lie down.. But if I belch the gas out (sorry,..) I'm then OK until I gas up again.
At first, this used to scare me, felt like a brick inside my lung, until I found 'the belch' eased it. But next day when the bloating has gone, I'm back to 'OK' normal.
You'll think I'm joking when I say beer doesn't cause it... but you'd think 'gassy.. and would', but it doesn't except if mixed with any of the above.
So what affects you? What do you do to get over it? Or you just don't eat what causes it?
