Do the tests the Neuro ordered and see what shows up.

If you do too many things at once you won't know which is working or not. You can watch your diet in the meantime and avoid sugar. That makes burning much worse for some people.

You can do a trial of gluten free and see if that works. Naturopaths often try to sell you lots of supplements to start, and you'd want to see how the B12 works alone, in the beginning.
You can always go later IMO.

You can have your doctor test your Vit D level too and correct that if it is low. Low D can cause problems.
