By the way....after googling that term Proprioceptive Dysfunction, it seems that people with this have other problems. I've never fallen or had trouble walking. And it only happened so far when I was sitting
Yes, this is a long-term dysfunction. I experience it -- I have little awareness of my left side, particularly my left rear -- a challenge when I try to transfer from chair to chair: I have to look to see where I'm "aiming" to be sure the chair is fully under me.
You certainly can go to whatever other MS sites you want..and the one you quoted is as good as any. I don't think you'll learn much more than you already know, though -- most of your symptoms are not typical of MS, you don't have many of the more common MS symptoms (trouble walking, balance issues, etc.), only those problemmatic vision problems.
Someone suggested you go to the lyme forum -- they provided a link in another of your threads -- because they thought your vision problems might be related.
And no, you don't have to have convulsions, or foam at the mouth, or even become unconscious, to have seizures. Seizures..like migraine headaches..come in a lot of different variants, and obviously cause neurological dysfunction. Think of your brain as an electric box -- if there is a "short" somewhere, even briefly, the lights will flicker. They may not go out..but they'll flicker. That may be what's happening with you.
