I am so baffled as I was diagnosed with MILD COPD about 12 yrs ago. Now I go to a diff dr as mine won't take my insurance and this one only had the girl make me blow into this little plastic gadget and when I got to see dr. she is telling me I don't have copd. I said so you are saying my dr. misdiagnosed me? She said NO, back then maybe you blew less, you did 101 today.I don't trust it, just can't change a diagnosis after 12 years. I have the chronic bronchitis part of copd and she says no, she thinks it is asthma. I don't want to go back to her, don't feel comfortable, help with suggestions.
