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.
When a blood clot stops blood flow to an artery in the heart or brain, a heart attack or stroke can result. Blood clots also can block veins in other parts of the body, causing conditions like varicose veins or pulmonary embolism (a life-threatening blood clot in the lungs). When a blood clot forms and stays where it forms, itâs called a thrombus.
