Complex. No short answer possible. With the long experience that i have, i would interpret it as a failure of cellular energy. Shortness of breath in the absence of lung disease suggests "oxygen hunger". I suggest that you read my blog "oxygen, the spark of life" that you can google it may change your mind about how medicine is supposed to work.
