Hello, thanks for using health care magic. Numbness results from irritation of peripheral nerves. There are diverse causes of numbness including metabolic conditions (such as diabetes), viral causes, Guillain Barre syndrome etc. It is not uncommon to find diabetics presenting with numbness. Diabetes is a chronic metabolic disease that can causes peripheral neuropathy. Treatment in the case of diabetes induced peripheral neuropathy relies on effective control of blood sugar level. 281 is high enough and you should aim at levels far below that in order to effectively control the numbness. You should also add vit b complex tablets and do an electrolyte profile tests. Best regards and hope this helps you. Dr Achuo
