### output:

Hi, Thanks for writing in. There is a possibility of diabetic neuropathy in you that must be investigated in detail. Diabetes itself starts affecting the nerves, eyes and kidneys in all patients having the condition for years. It is possible that you are experiencing the symptoms of diabetic neuropathy. Possibility of vitamin B 12 deficiencies must also be considered. In those taking oral glucose lowering medications like metformin, there is malabsorption of vitamin B 12 from the intestines. This can cause a chronic deficiency state and leads to symptoms like numbness and tingling in arms and feet. Please get examined by your doctor regularly and take vitamin B 12 supplements. This will restore vitamin B 12 levels to normal and prevent deficiency state. Please do not worry.
