It is possible that diabetes can cause foot pain. First of all, diabetes is a disease that has a negative impact on the body and can cause certain cardiovascular diseases in the body. Diabetic patients are prone to atherosclerosis and possible narrowing of blood vessels due to chronic hyperglycemia in the body. The narrowing of blood vessels may cause poor blood circulation in the body, and once the blood vessels in the feet are narrowed, it may cause foot pain. Second, the high blood sugar level of diabetic patients may affect the blood vessels, but also may compress the nerve line. Since the foot is one of the parts that are easily affected by the nerve cord, the body is prone to foot pain when it is in high blood sugar level for a long time. If a diabetic patient has foot pain, he or she needs to pay attention to it to avoid deterioration of the condition and more adverse complications, and needs timely treatment and conditioning.
