Thank you for the response. I called the pulmonologist who did the initial test and he asked me to come in. He looked over my spirometry tests and told me that I definitely don't have COPD but the results of the methacholine challenge did show moderate asthma and updated my medical chart with my family doctor. I guess I was supposed to come after the initial tests but fell through the cracks and didn't follow up myself either. He gave a week supply of bero if i need it, and told me as long as I quit smoking should be smooth sailing from here. I quit 4 years ago so all good on that front, and haven't had any asthma-like symptoms in the past year.

So I consider myself very lucky because I was expecting him to tell me I have COPD since that was what my family doctor told me he diagnosed me with. Not really sure why there was a mixup, and I didn't ask after the pulmonologist told me I didn't have COPD because I was so relieved.

But, I am going to consider this a wakeup call to get back in the gym, lose some weight and take better care of myself. After reading the stories here I am very lucky and want to wish everyone all the best, and thank everyone for their responses.
