In people with long-standing diabetes and hypertension, pain in both legs can occur for several possible reasons. One common cause is diabetic neuropathy (nerve damage caused by high blood sugar), which can make the nerves sensitive and lead to burning, tingling, numbness or pain, often worse at night. Another possible cause is reduced blood flow to the legs due to narrowing of the blood vessels, which may cause cramps or pain while walking that improves with rest. Muscle weakness, vitamin deficiencies, dehydration, or side effects of cholesterol or blood pressure medicines may also contribute. Less commonly, kidney-related problems can cause leg discomfort or heaviness. It is important to regularly monitor blood sugar and blood pressure and undergo a medical examination to assess nerve function and blood circulation in the legs. Simple measures such as regular walking, proper foot care, and avoiding smoking may help. Treatment depends on the exact cause and may include medicines for nerve pain and to improve circulation, along with lifestyle changes.
