Start out be learning what tests should be done for MS and other neuro things.... this is one:
http://www.neuroexam.com/content.php?p=2 Start at the intro and work your way thru. This gives you an idea of what docs look for when they test you.
Next is this: http://neuromuscular.wustl.edu/lab/nvworkup.htm#lab
Then check out ALL the neuro possibles? They are a lot!

This will help you keep an informed eye on what testing your doc is doing, as well. And I always make copies of the test orders, and ASK for a personal copy of the results so I can learn more about what tests were done and why-then what the results were and what they may mean.... The more you can 'check off' the lists? The better overall. From personal experiences? I've got several 'lists' and lots of overlap, making things harder to sort out. Not fun? But very interesting!

Do keep in mind? And wrack your brain here...that if you fell out of an apple tree at age 9 it 'can' show up on a brain scan ages later.... It's happened to me more than once with such tests and it can haunt you all your life, remembering all those forgotten falls and clunks can help docs zero in more efficiently on what your real problems are.

As for any immune issues? Such as MS or others, just remember, that we are all strong in surviving! We get by, and succeed inspite of these afflictions and we will keep fighting until we are better!

Have faith in yourself, learn the lingo and remember, there isn't a silly or stupid question on this stuff left to ask! So ask them and don't be shy, someone here has asked it and has an answer for sure!

Hugs and hope always! 's! - j
