Diabetic leg pain is a symptom of a condition called diabetic peripheral neuropathy, and it's something most diabetics eventually experience. The pain is the result of nerve damage in the leg caused by excessively high levels of blood sugar that occur when you have diabetes. Diabetic neuropathy can, if left untreated, become a serious complication that can lead to amputation or even death -- which is why treatment is so important. Most people who are living with diabetes can halt or slow the progression of diabetic neuropathy by being diligent in monitoring their blood sugar and taking their insulin accordingly and by pursuing healthy lifestyle choices. In addition, medications and other treatments can help people manage leg pain from neuropathy.
