Most of us probably take blood clotting for granted. But when a blood clot doesn’t dissolve, it can become dangerous—sometimes even deadly.
While you can develop a blood clot in just about any blood vessel in your body, clots are most likely to affect one of your legs, resulting in a condition known as deep vein thrombosis (DVT). If a clot breaks free from a vein in the legs and travels to the lung arteries, it can block blood flow and lead to a pulmonary embolism.
