What're the symptoms of pulmonary embolism?

The signs and symptoms of pulmonary embolism can vary greatly, depending on how much of the lung is involved, the size of the clot and your overall health - especially the presence or absence of underlying lung or heart disease.

Small emboli may not cause any symptoms, but most emboli cause shortness of breath, which comes on very quickly. Shortness of breath may be the only symptom, especially if pulmonary infarction does not develop. Often, the breathing is very rapid, and the person may feel anxious or restless and appear to have an anxiety attack. Larger emboli commonly cause sharp pain in the chest, especially when the person inhales; the pain is called pleuritic chest pain.

Other symptoms include increased pulse rate, dizziness, and fainting. If the lack of blood flow to the lungs has caused some lung tissue to die, called pulmonary infarction, the patient may also cough up blood-stained phlegm, have sharp chest pains, and fever. When the larger vessels of the lungs are blocked, the lack of oxygen gives the skin a bluish color. Patients with chronic pulmonary embolism, where small blood clots travel to the lungs repeatedly over a period of years, will have symptoms that build up gradually, including shortness of breath, leg swelling, and general weakness.
