Hi, thank you for query. It is a normal symptom of heavy exertion but becomes pathological if it occurs in unexpected situations In 85% of cases it is due to either asthma, pneumonia, cardiac ischemia, interstitial lung disease, congestive heart failure, chronic obstructive pulmonary disease, or psychogenic causes Treatment typically depends on the underlying cause. The initial approach to evaluation begins by assessment of the airway, breathing, and circulation followed by a medical history and physical examination. Signs that represent significant severity include hypotension, hypoxemia, tracheal deviation, altered mental status, unstable dysrhythmia, stridor, intercostal indrawing In those who are not palliative the primary treatment of shortness of breath is directed at its underlying cause eg, cyanosis, and absent breath sounds. You should consult to physician for proper work up and exact treatment.Dont take medrol without proper investigation.
