A significant feeling of heaviness and soreness in the right leg is considered to be caused by venous system diseases, including varicose veins and deep vein thrombosis in the lower extremities, which in many cases are secondary to prolonged exertion or weight bearing, and can also reveal superficial vascular tortuosity, dilatation, and even thrombophlebitis. Patients can also experience increased local symptoms after activity, and in severe cases, skin ulcers and even necrosis can occur, requiring further surgical options if necessary. There are many reasons for the formation of venous thrombosis, including patients who are bedridden for a long time, after major surgery and internal fixation of bone fractures in the extremities, as well as damage to the local lining of the lower extremities caused by trauma, which can easily lead to secondary thrombosis of the deep veins of the lower extremities.
