Two years ago I was diagnosed with severe optic neuritis. Although I am at high risk for ms, because my father had it, my consultant advised me to wait to see if any other symptoms develop before doing any tests. No drugs at all were prescribed.
Since then, I have been taking high doses of vitamin d, plus linseeds, lecithin, and essential fatty acids. So far (touch wood) I have had no other symptoms, other than very poor short term memory which may or may not be related.
It does seem, if you look around, that a lot more people have some minor versions of symptoms associated with ms than are actually diagnosed with it, no different from what some of the people with "benign ms" seem to have, but without having bothered to look into it. The either/or of ms may be wrong -- it seems that there is a very big continuum of symptoms, and some of the people who are being medicated might never have had any progression.
