Symptoms of leg blood clots in the elderly usually manifest as swelling, ischemia, and pain in the lower extremities. When elderly people have leg blood clots, it may lead to poor blood circulation in the legs and symptoms such as obvious swelling and movement disorders in the limb area. If the leg blood clot belongs to the venous embolism, it will easily cause the reflux of the veins, and the elderly leg will have obvious swelling, bruising and other symptoms. In addition, if the elderly leg thrombosis belongs to the arterial embolism, there may be a sudden onset of coldness, pallor, numbness, pain and other symptoms in the limb. As the condition worsens, symptoms such as impaired limb movement, limb ulcers, and limb infections may also occur. Elderly people with leg thrombosis should go to the hospital in time and be given appropriate treatment and therapy under the guidance of the doctor in order to avoid delaying the condition.
