I've had asthma my whole life. There has been improvement thanks to better fitness and allergy shots, but lung congestion is still a chronic problem.
I'm 99% sure it's lung congestion which is the problem because I don't wheeze, but I'm definitely not getting enough oxygen. When I exercise, I usually get pale, with dark bags under my eyes, which I believe is either caused by not enough oxygen in the blood, or not enough of the waste being removed from exhaling. I can often feel it even when I'm not exercising. The BIGGEST clue that congestion is the problem is that on the RARE occasion that I get a deep, clearing cough, there's huge and immediate relief.
Other than the medication which I’ve listed, I've tried drinking guaifenesin (the drugstore stuff for chest congestion) and lots of water, with limited success.
So, my question is... what else could I be doing or taking to help remove/prevent this lung congestion? It's very deep down, and hard to get out.
