hi there, welcome to the forum. unfortunately i can't help you with the health care system ins and outs that you're facing.
all i can help with is ms nutrition info, myself. do you have any resources available for getting some tests done and buying any supplements that could be needed?
lef is having a sale apparently, til jun 4 - http://www.lef.org/BloodTest
how to order http://www.lef.org/Blood/index.htm#how
test list http://www.lef.org/search/product-categ ... index.aspx
here's a good one to know (magnesium): http://www.lef.org/Vitamins-Supplements ... -Test.html
and zinc: http://www.lef.org/Vitamins-Supplements ... -Test.html
and another worthwhile test too: http://www.lef.org/Vitamins-Supplements ... -Test.html
all three are low in your typical ms patient, and these nutrients are linked to diverse and wide ranging health effects including neuropathy, eye trouble, pain, confusion, fatigue, tremors, memory, all the things you're talking about.
there are other nutrients that are low in ms patients too, but if i had to choose three i think it would be those. although depending on your diet i might also suggest b12.
do you think any testing will be possible for you?
