Hello Heather! I was diagnosed all of my adult life with asthma and put on inhalers. I have been going to the Mayo Clinic since 2013 and they have never mentioned me having asthma and it is not in my medical records either. So, I do not know if I do or not. I nebulize albuterol daily, so it really doesn't matter either way. I have a feeling that I went for many yrs with serious lung issues and it got blamed on asthma. I was treated short term for recurring pneumonia over the yrs, and I have a feeling it was mac or pseudo instead, My sputem was never tested back in the day; so, who knows??
