I just tested low for Vitamin D, but not terribly low. I live in Ohio, and here, too is a higher rate of MS. We don't get a whole lot of sun due to the terrain.
Hi Trace,
Vit D deficiency can mimic MS symptoms and is also suspected by some as contributing to the disease itself. The further you get from the equator (sunlight and its supply of Vit D) the greater the occurence rate of MS in the general population. Canada and the UK have very high rates.
You should take a look at some of the other common mimics too. We have them listed on our health pages - here is the link -
