Re: Asthma, COPD, Acid Reflux, allergies... how can you tell?
There are some specific questions doctors can ask to determine causes. Some folks, though, have multiple issues - I have many allergies and any of those can cause asthma attacks as well as exposure to cold air and exercise.
It is best to start with your regular doctor. He/she can ask you the right questions to advise what type of specialist might be able to help you the best.
I go to a pulmonary practice that also does allergy - So I'm pretty well covered that way.
