I am sorry that you remain in "limboland" a very frustrating place to be.

Have you had your B12 level checked? Even if it is "normal" you may still be deficient. I had (have lost touch) a friend who was diagnosed with MS and it turned out what she truly had was dangerously low B12.

If they are testing for MS, did they test your vitamin D level too.

Don't overlook the possibility of Lyme disease or celiac disease either. There is a secton on MS, Lyme and CD in The Gluten File. This is really a part of The Gluten Sensitivity/Celiac Disease forum here on BT2. http://jccglutenfree.googlepages.com/multiplesclerosis

Hope you find answers.
