Blood clots become more common as people get older, especially when they are over age 65.
Moreover, you can be at higher risk if you have a family history of blood clots.
The Mayo Clinic says pulmonary embolism symptoms “can vary greatly” depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease.
It adds that there are several common signs and symptoms, some of which may show up in the leg, skin and chest.
