Foot pain in diabetic patients may be seen for several reasons. First, neuropathy in diabetes. Nerve damage occurs in diabetic patients due to increased oxygen free radicals in the body, toxic effects of high blood sugar, and impaired microcirculation. Neuropathy in diabetes often involves the distal extremities and results in numbness, scratching, and pain. Therefore, diabetic patients with neuropathy will experience foot pain. Secondly, it can also be seen in diabetic vasculopathy. When diabetic macrovascular disease involves the peripheral arteries, it can cause narrowing or occlusion of the blood vessels, resulting in insufficient blood supply and causing pain in the limbs. Finally, diabetics with foot pain should also be alert to diabetic foot, which is usually caused by a variety of reasons, including the involvement of neuropathy, vascular disease, and the involvement of infectious factors. When diabetic foot appears, you need to go to the hospital in time for comprehensive treatment such as controlling blood sugar, controlling infection and improving circulation.
