I was having coughing and phlegm issues, so I went in for diagnosis. At that time, I too was diagnosed with COPD which was several years ago. Knowing COPD is a progressive illness, and I was not getting any worse, I decided to get retested about 6 months ago. Guess what, they informed me I do not have COPD by I have age onset asthma. So instead of treating me for COPD, they are treating my asthma. I am still fighting with Phlegm issues. I really doubt if I ever find anything that will help. Good luck.
