The moment a clot migrates to the lungs, it becomes a pulmonary embolism—a medical emergency of the highest order. One of the primary symptoms is a sharp, stabbing chest pain that may feel worse when you take a deep breath (pleuritic pain).

It is frequently confused with a heart attack, but regardless of the cause, any sudden, intense chest pressure requires an immediate call to emergency services.
