There are different types of embolisms. Pulmonary emboli are probably more widely known, occurring when a blockage hits a major artery of the lungs.
An embolism can cause a heart attack, stroke, headaches, and vision and speech problems. Other symptoms: coughing, chest pain, dizziness, and paralysis. If you have a clot in an extremity, you may not feel a pulse below the clot since the embolism has restricted or blocked circulation.
