hey there folks sorry you're having a rough time. i don't know how i lucked out but it was kind of a whirlwind diagnosis for me and STILL the waiting was agony so i really feel for you guys.
cheer has wise advice to get you started on action for the right now.
if your symptoms are eye related i wonder whether you're getting enough protein, vitamin A, zinc, and b-complex (B1/thiamin in particular). you can look into which if any of those might be low in your diet, or depleted for some lifestyle reason (for instance some prescriptions drain certain nutrients etc), and take action as appropriate.
a b-50 complex will help you combat stress while you wait for news.
if you're on the hook for possible ms, they need to check the following, in descending order of importance
(with b6, subclinical b12 deficiency affects cognitive function and stress levels before any neuropathy shows up - the lab results will come back "normal" right down to 200pmol/L but you can aim to keep it above 500 for better cognitive function)
(ppl with the lowest risk of ms have levels 100nmol/L or higher. probably a lot of docs will still say you're okay down to somewhere in the 70s or lower, so make sure you know the results yourself).
(the normal range is 11.5-18.5 μmol/L, optimal is 18. most folks with ms are lower than that you can search here for the topic ms, zinc, boys, girls, controls to read more)
(this one is a neat indicator of your body's natural antioxidant status. the normal range is something like 140-340, they'll tell you you're fine anywhere in that range but in fact the ms average is 190 and healthy controls are 290. i'm working on figuring what link if any there is between zinc intake and uric acid status. anyway if you are interested i wrote up a little ms blurb on the uric acid page of wikipedia http://en.wikipedia.org/wiki/Uric_acid
once you have baseline numbers for these you can set up a plan to address any probs that turn up.
hope that gives you a better sense of control over the right now! you can start supplementing and making diet mods any time you like - and it's still good to get a couple of tests and followup tests to make sure you don't overdo anything. if you need more details just say
