Even though I've spent the last 30 plus years of of my life living with a debilitating chronic illness and dealing with just about every kind of medical professional imaginable, I find that I don't have any advice for you except this...

Never give up on your daughter. She's so fortunate to have such a caring and concerned mother. That fact will help her almost as much as any help she gets from the medical community.

My illness mimics MS in many respects and several medical professionals have thought it might be MS. But I have never recieved a diagnosis of MS, so I don't have any advice for you on how to deal with it, or even how to get a diagnosis. I see that there are several others here who have a lot to offer you in that respect, however. Good luck to you and to your daughter. Here's hoping for the best possible outcome for her.
