This may be caused by peripheral neuropathy due to diabetes, presenting as burning, electric shock-like, or stabbing pain in the calves, or sharp, sour, cold pain. Peripheral neuropathy is a common chronic complication of diabetes, usually starting in the lower limbs, characterized by numbness, dullness, or hypersensitivity in the hands and feet. It may also be caused by diabetic lower limb vascular disease, leading to calf ischemia and hypoxia, causing pain, intermittent claudication, and in severe cases, black or purple feet.
Recommendation: If these symptoms appear, seek medical attention as soon as possible.
This may be an early sign of diabetic foot. Diabetic foot is caused by long-term high blood sugar levels damaging the nerves and blood vessels in the feet, leading to poor nutrition, sensitivity, and vulnerability to infection, resulting in localized tenderness or pain.
Initially, it may present as localized tenderness or pain, but if not taken seriously and treated promptly, it may progress to ulcers or gangrene.
Recommendation: If foot pain occurs, especially with redness, swelling, fever, or signs of infection such as skin damage, seek medical attention immediately. Additionally, diabetics should take good care of their feet, keep them clean and dry, wear comfortable and breathable shoes and socks, and inspect their feet for any abnormalities after washing them every night.
