Well I would say that you should start taking some Vitamin D right away. And especially if you live North of the equator where there is less sunlight! I was experiencing numbness in my right foot and then it spread to my left foot. I have had digestive problems in the past too which led me to suspect that it was a deficiency of some type. I went to a Neurologist who asked me a bunch of questions and sent me for an MRI. I have yet to get the one done on my brain. But I was not receiving the help that I really required between a bunch of different quacks (I call Doctors quacks because most of them are idiots). My numbness was spreading far too fast so I decided to do some research on the internet and found that there is definately a link between MS and low Vitamin D levels. I then got some Vitamin D and took 2,000 UI and found that within about 4 hours time the new numbness that had started appearing in my hands had suddenly disappeared! I then decided it was time to request that I got a Vitamin D blood test done only to find that the quack I went too "didn't want to do the test "saying that "it would cost our healthcare system $145.00 and that that was too much money!" I then asked her, "So my life is not worth that amount?" She then decided to do the test after I added, "Well I do have digestive problems so I would like to get it checked please!" We are talking about the Canadian Healthcare system whereby some quacks(doctors) would rather refuse you a test because they say "it costs too much money" than the prospect of doing some volunteer work for one or tow afternoons a month! I had also told the silly quack that, "An MRI test costs a hell of a lot more than a simple blood test does!" And this is frankly just one more reason why I don't call quacks doctors! Since no one in Africa gets MS until they move to somewhere that the sun doesn't shine that much there is one big key there....which is the amount of sunlight that you are getting....and hence the amount of Vitamin D you have in your body! You may wish to try taking Vitamin D if you have any auto immune problems too! Vitamin D regulates your immune functions. So please get a Vitamin D blood test to see where your levels are.
