As ClotCare explains, a pulmonary embolism is a life-threatening condition. Symptoms include difficulty breathing, shortness of breath and chest pain. Immediate medical treatment is required.
Factors that increase the risk of getting a blood clot in the legs include prolonged immobility and bed rest, obesity, varicose veins, cancer, major injuries, long-distance travel, estrogen replacement therapy, and pregnancy and child birth.
