I suffer from shortness of breath/breathlessness where it feels like no air is going in. SOB all the time, but worse when I exercise. Feels like I'm being smothered slightly. Sometimes dry cough that comes and goes. Also feel tired/weak.
PFT normal. Although, dlco likely underestimated, but have had this problem on 2 PFTs where it has been slightly off. But I am not sure if that means something or just nothing. Dr didn't seem concerned, so I think it's just normal.
Can other tests show things wrong with the lungs or do PFTs always show everything? What other tests would be recommended?
