Hello! Welcome on HCM! Regarding your concern, I would explain that your symptoms seem to be related to peripheral neuropathy, probably caused by diabetes. For this reason, I would recommend performing a nerve conduction study to examine the nerves in your limbs. In fact the nerves are not in the head, but in the limbs. If the nerve conduction study results normal, the next step to follow would be a brain MRI to exclude brain small vessel disease, which is another common complication of uncontrolled diabetes. Anyway, you should know that a better control of diabetes can stop the progression of your troubles. Hope to have been helpful! You can ask me again directly if you have any other questions! Best wishes, Dr. Aida
