As people get older, they become weaker and weaker and suffer more and more from various health problems, and leg pain is even more common among the elderly. Many elderly people tend to think that leg pain is a problem of joints and bones, and rarely consider the possibility of other diseases causing leg pain, and diabetes is one of them. Six months ago, 60-year-old Ms. Wu felt numbness, pain, sock-like sensation in both lower limbs, and her legs became stiff. Ms. Wu suspected that she was a lumbar disc herniation, and went to the hospital for several months to treat her leg pain, and then was advised to go to the Department of Endocrinology and Metabolism to identify the cause, which turned out to be leg pain caused by diabetes. Shen Jie, vice president of the Third Affiliated Hospital of Southern Medical University and director of the Department of Endocrinology and Metabolism, explained that the reason for Ms. Wu’s leg pain and weakness is that diabetes causes atherosclerosis and other lesions in the blood vessels of the lower extremities, which reduces blood flow to the lower extremities, especially during activities, due to increased oxygen consumption in the muscles and bones, but the blood flow in the blood vessels of the lower extremities is seriously inadequate, which leads to increased ischemia and hypoxia, resulting in lower extremity Pain. Shen Jie introduced, diabetes caused leg pain is usually a long history of patients, these patients will also be accompanied by many other complications, such as blurred vision, dizziness and weakness. The leg pain caused by diabetes should not be taken lightly, if not treated in a timely and regular manner, it is very likely to cause diabetic foot, diabetic complications peripheral vascular disease and diabetic neuropathy. Sugar lovers with leg pain should have ultrasound examination of lower limb blood vessels and neurophysiological examination in time to make a clear diagnosis. The treatment for these patients is mainly to control blood sugar, while painkillers can be taken to reduce pain, and some nerve-nourishing drugs can also be taken. For patients with combined lower limb vascular lesions, it is appropriate to enhance vasodilatation and antiplatelet therapy. For middle-aged and elderly people, if leg pain occurs for no reason, the possibility of diabetes should be considered after excluding other diseases. Experts remind that leg pain caused by diabetes is usually bilateral, plantar dominated, and can be accompanied by itchy skin, numbness, etc.; while arthralgia is only localized joint pain; leg pain caused by lumbar disc herniation is usually unilateral.
