Pleuritis and Pulmonary embolism are other possibilities causing shortness of breath with
chest pain. A CT scan of the
chest can rule out both. Another possibility that can explain the
pain is pericarditis. It causes chest pain aggravated by laughing yawning and deep breathing and also causes radiation of pain to arms. Again an EKG, heat echo and chest X-ray is required. Of these pleuritis, pulmonary embolism (especially this) and pericarditis cause breathlessness as well.
