For the past week or so I have been struggling with what I think is air trapping. It feels like getting squashed from within. Sitting upright is downright unpleasant as it feels like I am bending over my ribs. I (feel like I) need to take big "gulps" of air to get enough, but at the same time I am risking to hyperventilate due to the slow emptying of air from the lungs.
Sounds familiar to fellow members with emphysema?
