There are many conditions that can cause leg edema if there is no trauma, such as obstructed venous return in the lower extremities and arthritis can cause it. Varicose veins are simply varicose veins that occur due to increased pressure in the veins of the legs. You can see the worm-like varicose veins under the skin of the lower leg. Wearing elastic stockings can relieve the symptoms and prevent the occurrence of lower limb phlebitis. If it is a heart problem, there will be shortness of breath during exertion, it is recommended to go to the hospital for examination and treatment so as not to delay the treatment, and also to exclude the possibility of hypoproteinemia. If there is a history of prolonged standing and sedentary work, consider the swelling caused by poor blood return to the lower extremities due to reduced blood circulation. Such swelling can be improved by elevating the patient’s limbs and paying attention to rest.
