Hi Caroln, and thanks for your post/inquiry. Generally speaking, a specialist/pulmonologist may be the best category of doctor for you to see. A pulmonologist is specially trained and experienced in the treatment of pulmonary diseases, including COPD. I am curious as to what type of chest specialist you saw for which you experienced disappointment.
You may want to also consider seeing the doctor who prescribed the CPAP machine for you so many years ago. Have you been back to see that physician since then?
What do you think?
All the best,
Leon (site moderator COPD.net)
