@tim Hello, Deep vein thrombosis (DVT) is a blood clot that develops within a deep vein in the body, usually in the leg. DVT usually occurs in a deep leg vein, a larger vein that runs through the muscles of the calf and the thigh. It can also occur in the pelvis or abdomen. Anything that prevents your blood from flowing or clotting normally can cause a blood clot. Contact your doctor if you have again had its symptoms. Thanks!
