Get StartedSymptoms
By Mayo Clinic staffPulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clot and your overall health — especially the presence or absence of underlying lung disease or heart disease.
Common signs and symptoms include:
- Shortness of breath. This symptom typically appears suddenly, and occurs whether you're active or at rest.
- Chest pain. You may feel like you're having a heart attack. The pain may become worse when you breathe deeply, cough, eat, bend or stoop. The pain will get worse with exertion but won't go away when you rest.
- Cough. The cough may produce bloody or blood-streaked sputum.
Other signs and symptoms that can occur with pulmonary embolism include:
- Wheezing
- Leg swelling
- Clammy or bluish-colored skin
- Excessive sweating
- Rapid or irregular heartbeat
- Weak pulse
- Lightheadedness or fainting
When to see a doctor
Pulmonary embolism can be life-threatening. Seek immediate medical attention if you experience unexplained shortness of breath, chest pain or a cough that produces bloody sputum.
