i would like to know as much as possible about nerve damage that can be coursed by type 1 or 2

It is my understanding that taking B vitamins help support your nervous system and try to prevent damage.  Otherwise keeping a check on blood sugar levels and looking after yourself is the best course of action.

Have you been told you have diabetes or that you have nerve damage. If diabetes is it type 1 or 2, how is it controlled and is it well-controlled. Diabetes if it is not well-controlled can definitely cause nerve damage

I had foot nerve damage for many years.  Some days extreme pain.  I was diagnosed diabetic type 2 in 2015.  I take 1 metformin per day, but have attacked the disease using my own research and experimentation.  Nerve damage may be caused by high glucose levels but also by high insulin levels.  Most doctors will not check for high insulin levels.  It is caused by insulin resistance, when the blood cells stop allowing glucose and insulin to enter.  I manage both by increasing my vegetable intake every day.  Then I eat only 3 meals per day and fast 3 hours between meals to allow glucose and insulin to clear out of the blood stream.  I can now work all day without even thinking about my feet.  To make faster progress, fast 1 day per week and only drink vegetable juice all day.  It does not affect glucose levels.  And plenty of clean filtered water every day.  John
