Hi, I was diagnosed months ago by my GP with COPD. At that time I started taking Advair, which helped a lot. Problem was it caused me to have vertigo so I had to change meds. Recently I went to a pulmonologist and she did a thorough breathing exam. The test results that she obtained indicated that I have asthma primary with mild COPD. She has change my meds again, I now use a rescue inhaler, oral prednisone and dulera. I am not seeing a lot of improvement and she advised me that if there wasn't a major improvement I might have to be referred to a cardiologist. Has anyone had similar experience? Why is it so difficult to diagnosed and treat? I have also been told if asthma is treated as COPD and visa versa that is not good. Any ideas out there?
