One option, if you have the means and can collect the mail from your parents' house, is to go ahead and pay their bills yourself -- it's not illegal to pay someone else's bills.
Pulmonary embolism occurs when a clump of material, most often a blood clot, gets wedged into an artery in your lungs. These blood clots most commonly come from the deep veins of your legs. This condition is known as deep vein thrombosis (DVT). In most cases, multiple clots are involved but not necessarily all at once.
Blood clots in an artery (arterial thrombi) occur by a different mechanism. For those with atherosclerotic disease, plaque deposits form along the lining of the artery and grow, which causes the vessel to narrow. This disease process may cause: 1  heart attack, 2  stroke, or. 3  peripheral artery disease.
