Welcome Roz, so nice to have you here. I am so sorry for your recent DX of MS, but so glad you found us.
After you have been DX, I see no need for an LP, unless your Doc wants to rule out something else. The LP findings that point to MS ar Banding and protien in the spinal fluid + other things, of which,I'm not familiar.
So sorry about you DH's disability, as well. The two of you have quite a challenge in front of you. If we can be of any help and comfort, do not hesitate to let us know.
In the meantime, please join in anywhere here and enjoy being a part of our Family.
