<s>[INST] For 3 years I have had cold feet summer and winter.  I am diabetic for 3 years, back problem which has damaged my nerves in my legs.  Recently my feet are warm to touch in the area of the front foot behind the toes and they are not cold.  Is something better or worse? [/INST] Hi,Thank you for your query. I can understand your concerns.Persistent cold feet in a diabetic could be due to peripheral arterial disease due to premature atherosclerosis and consequent narrowing of arterial lumen. In such case foot pulses will be weak.The ankle-brachial index (ABI) can be measured to detect the severity of peripheral arterial disease (PAD).Regards Dr. T.K. Biswas M.D.Mumbai </s>
