As the saying goes, people old first old feet, feet is the second heart of man. Many people have cold legs and feet, numbness, walk a section of the road feel pain, have to rest; and then walk, but not long after the pain, but also have to stop and rest. If you find these symptoms, don’t take them lightly, and don’t think that “old feet come before old age” is a normal phenomenon of old age, but in fact, it is likely that atherosclerosis is creeping up on you. Early Symptoms Atherosclerotic occlusive disease is a manifestation of atherosclerosis. With the development of atherosclerosis, atherosclerotic plaques continue to expand and secondary thrombosis, resulting in narrowing of the arterial lumen or occlusion of the limbs, causing acute or chronic ischemia, known as atherosclerotic occlusive disease. Atherosclerotic occlusive disease of the lower limbs is one of the most common diseases. Due to insufficient blood supply, the patient’s lower limbs unilaterally or bilaterally will have a series of symptoms such as coldness, numbness, leg muscle spasm, and soreness after exercise or even at rest. Self-diagnosis Elderly friends can early self-diagnosis: such as the appearance of frequent walking a few hundred meters after the calf stomach pain, or feet cold, then you should look at the foot skin color, lower limb ischemia when the foot skin color is often whitish, or purplish-red, but also feel the temperature of the feet, if there is a disease of the feet will be cooler. And can feel the dorsal artery of the foot there is no pulsation, if the arterial pulsation is normal, can be ruled out, if the dorsal artery pulsation is very weak or disappeared, the likelihood of suffering from this disease is very high. At this point the patient must go to the hospital. Do not miss the treatment time because to the late stage of the disease, the arteries may even evolve from hardening and narrowing to complete occlusion, then even at rest the limbs are in extreme ischemia, the nerve endings produce severe pain called “resting pain”, especially at night and winter and spring seasons when the temperature is lower symptoms are serious. At the same time, skin and muscle tissue ischemia makes its vitality gradually lost, and eventually there will be ulcers on the affected feet, especially toes, or black gangrene, and the recurrent infections of necrotic parts are often uncontrollable with general medicines, which will result in the so-called “old rotting feet”, and at this time, if you go to hospital again, you will have missed the best time to treat the condition, and even though the blood flow of the residual limbs can be improved, necrosis has already occurred. Although it can partially improve the blood flow of the residual limb, the part of the limb that has undergone necrosis still needs amputation. Reminders for life 1, minimize going out in cold weather, or wear more clothes when going out, pay attention to keep the limbs warm. 2.Regular treatment of primary diseases, especially hypertension, diabetes, hyperlipidemia, etc., with emphasis on standardized medication. 3.Combine work and rest, pay attention to rest well. 4.Strengthen the activities of both lower limbs appropriately to accelerate blood flow and increase blood supply. 5, once the double lower limb pain aggravation can not be relieved in a timely manner to the hospital examination and treatment, so as to avoid the tragedy of necrosis and amputation of the affected limbs.
