Sorry to hear about your COPD. Lung disorders and diseases can be very straining not only on the person with them, but also the families. My wife suffers from Acquired Bronchiectasis (bron-key-ek-ta-sis). For years we have been fighting doctors over her condition, first they said Asthma with no testing, then it was Pneumonia, then with actual testing (ct/blood) they tried to say it was COPD. After all of this my wife was still untreated with only a rescue inhaler. I became completely fed up with the lackluster attempts and plain ignorance of the physicians the Military had to offer so I began my research. After compiling multiple cases with similar symptoms I came across Acquired Bronchiectasis, I immediately contacted her physician with my findings and he thought I was some "crazy know-it-all" (his exact words). When my wife was finally correctly diagnosed with Acquired Bronchiectasis I made an out of the way trip to the NAVY hospital to rub it in his closed minded face. I really hate when physicians just don't care enough to find the problem but instead attempt to put band-aids on bullet wounds.
I understand where you are coming from Tom, we have been in your shoes. Best advice I could give is to get monthly to bi-monthly blood work done to check on your blood cell counts and iron levels. Eat vitamin C daily and try to keep your calcium up, I am guessing your second inhaler is Advair. If you haven't been talked to about and or taken Prednisone, ask your doctor about it. Prednisone is a steroid that will help with increased air flow in the respiratory system. Also look into allergy medication to help with flare up's from dust/pollen such as "Cetrizine(ZYRTEC)" and "Montelukast(SINGULAIR)".
Hope this helps, if you ever need someone to talk to I am available 24/7-365.
Hoping for the best,
Drew
