Hello, I've done 4ct scans, 2x rays, 2 endescopes, I'm taking acid reflux ppi drug. I've done 2 spirometry tests in the last 4 years that are normal. I quit smoking 5 years ago. All the above years in the last 4 years. I have mild emphysema. I'm coughing allot and my breath is sometimes cut off when i inhale deeply. The 1st pulmanologist said it was gerd. The gastrologist after 4 years said nothing more he can do. He doesn't think it's gerd. Now second pulmonologist after spriometry days is not copd. Going for asthma test in two weeks. I'm not convinced it's that. Not really coughing up anything. Thoughts?
