Hello, Welcome to Just Answer and thanks for your question. Asthma is one possibility. Allergies are another and anxiety is a third. Of course only the providers who can treat you in person and order testing can tell you why you are having this symptom. It sounds like they are working on a diagnosis. A pulmonologist is the specialist to consult.
yes, seeing specialists, but it's been a few months and no diagnosis, so I'm looking for more ideas
allergies were ruled out, my lung function test shows some minor inflammation in small airways, doc says could be asthma, or could be from bronchitis taking a long time to heal
with a person with mild asthma, is this type of symptom typical? shortness of breath every day for months?
If tests have shown that it isn't asthma or bronchitis, then that definitely means that it is something else. What that "something else" is would be what your treating physicians are going to have to find out. For one thing they can measure whether you are actually low on oxygen versus you have a feeling that you are low on oxygen. That can determine if it is purely a physical problem versus something like anxiety. The latter makes someone "feel" as though they are short of breath even though they aren't. Anxiety can be constant or only cause intermittent problems.
Your providers can try a mild anxiety medication for a month or two and see if that eliminates the feeling of shortness of breath. It appears that they are going through the diagnostic process one by one and finding nothing serious at all.
