Yes lightening has been reported helping MS...if they live to tell about it. And I tried magnets to help heal brain lesions. By Dr. William Philpott. He also has a book called "Brain Allergies" you may be interested in. He was the first Doctor to tell me I had MS, right off the bat...the others took years to give me a diagnosis.
Since you shared your thoughts on food allergies , I thought I would share my theory on why I came down with MS. I had been on the original aktins diet for a whole year, which is meat, fats and very little veggies. I had the best blood work up ever due to that diet. I then read a negative report about the diet and got spooked that I may be doing damage to my health, even though I was doing well.
I was not knowledgeable enough to know that I should have weened myself off the diet slowly. I just jumped right into a vegetarian diet...and within a week, I was weak as a kitten and so brain fogged I couldn't think straight.
My theory is that going a year without any Sugar and carbs, then adding it suddenly to my diet brought on inflammation...especially to my brain, in a big way.
The good news is brain lesions can heal. After my last MRI, they said some of mine were gone and a couple got a little bigger. I have not been back since. I sure would like to know how I'm doing but I'm just going by how my brain works these days instead.
