I still say a doc should be slow to order any X-ray! Your chances of cancer go up with every X-ray. You cannot rule out pneumonia without an X-ray, however. But if the doc strongly suspects pneumonia, he can go ahead and treat it without an X-ray. An embolism is an emergency condition. This was probably in an ER?
The X-Ray was. Severe chest pains, shortness of breath and coughing with blood.
ER diagnosed Pneumonia. I was released after 5 hours.
Doctor the next day ordered a CT which revealed the culprit.
Multiple PE.
