The symptoms of numbness of the finger and toes in a diabetic are suggestive of diabetic neuropathy. This is result of the micro-vascular injury to the nerves and vessels due to diabetes. Even though you have mentioned an a1c level of 5.5, which is normal, I would suggest that you visit your doctor for a complete physical examination. If a diagnosis of peripheral neuropathy has been made, drugs like gabapentin, tricyclic antidepressants and SSRIs may be helpful in the treatment of symptoms.
