I hadn't had bronchitis for over 10 years. In July I got bronchitis and I didn't go to the doctor for it and once I did my doctor thought I had pneumonia. He had me go to the hospital from his office. Once they found out I smoked they immediately determined I had COPD even though my lungs were perfectly clear in the X-ray. I made an appointment with a Pulmonologist to get their opinion but I'm concerned that I was mis-diagnosed simply because I smoke. Does that happen very often?
