A sudden blocking of an artery.
An embolism is the sudden blocking of an artery. This may be caused by a mass of clumped blood (clot), fat, or an air bubble.
Weakness, pain, numbness, and coolness of the arms or legs are some symptoms.
An embolism can be life-threatening, blocking blood flow to the brain, heart, or lungs. Prompt medical treatment reduces risk of death.
