MS take years to develop for lots of us, and it is not easy to diagnose in beginning--I can't even count how VERY many doctors I've seen over the years, trying to find out what was wrong--it is that history over the years that for some of us is what finally gets the diagnosis made.
Again, ask you dr for a referral to an eye dr (or just forget your doctor
and go straight to an eye dr)--as I said, it is a neuro-opthhalmologist that often is the one that you get a diagnosis from--they run all sorts of tests, and then do send you to a neuro, but a neuro I find is useless in a case like yours--it is the neoro-opthalmologist that is the crucial one to see when it is optic neuritis (which yours sounds like). Bring your blood tests with you.
Many of us do have liver problems also, but "offical" literature has little on this.
