Nope,not me, April. Mine was possitive for protein. I had a Myeliogram.

Thats what they did, in the old days, before MRIs.
I have heard from others though, that their LP didnt show anything, and yet was DX by other tests. Some Docs want a whole battery of tests before they will DX MS and some will do it with one.
If you get a DX with an MRI and/or other means, an LP is an unnecessary danger and discomfort.
