I have a problem with p.e what is the course of treatment?

Pulmonary embolism?: If you are referring to a pulmonary embolism (blood clot in the lung), it is usual for a patient to be put on the blood thinner, heparin, and a little later - coumadin (warfarin). Your doctor will help evaluate the likely source of the clot - often by doing a dopper exam of your legs. It's also important to determine risk factors: medications, genetic factors which predispose a person to increased clotting.
