Alyson you gave me this idea. DVT stands for deep vein thrombosis. PE stands for pulmonary embolism. Thrombosis is the formation of a blood clot. A blood clot is a thrombus. An embolism occurs when that blood clot dislodges and moves to another part of the body. When there is a blood clot somewhere, there might be a stroke in the future. When I was working as a PT, I had this paper at my desk stating the risk of a DVT or PE. Now, I had a blood clot somewhere in my body and had no symptoms whatsoever. I didn’t have any of these risk factors either. Like I’ve said before, sometimes s*** just happens. But there are signs.
