I hope you can find a good doctor that understands these tests. Finding the very basic vitamin levels and getting them up is SO important. A first important step.

Get new testing and then have someone help you test again after being on the supplements.

You might want to read the book "Minding my Mitochondria" by Dr. Terry Wahls. She has a lot of good videos also. She helped her MS that was very bad with food and supplements. I am not saying it would cure everyone, but it is very important to get all of the micronutrients and vitamins and minerals that help the myelin and nerves grow and heal.
