None of this sounds familiar to me. I never experienced vertigo, although I think that some people with MS do, and I have never had any localised numbness.
I'm a vegetarian too. This makes things slightly easier for me because avoiding all saturated fat eases the stiffness in my legs somewhat and meat and dairy, generally speaking, are loaded with the stuff.
I'm not really too familiar with MS symptoms that I myself don't have but I'd guess that it isn't MS in your case.
I'm always droning on about vitamin D3 but I feel that I ought to mention it.
Very high doses (10,000 iU+) have been shown to be effective in combating MS, in that they make the likelihood of a relapse slimmer, an MS event slimmer. It also protects you against many other maladies so you do yourself a lot of good besides safeguarding against the possibility of MS.
