Hi Lymiegal, Welcome to Neurotalk and the MS forum. I second the others about the Lyme issues and getting that under control. I know that the infection from the Lyme can cause MS to be more symptomatic as does any infection so maybe getting the Lyme under control/or eradicated might give you daughter a chance to get a grip on the rest of the her symptoms.
In addition, it might give the docs a chance to treat, or maybe get a better handle on what type of symptoms she's having with her MS.
You might want to check out the National MS Society's website for symptoms and treatment.
www.nmss.org They have some good info for the newly diagnoses. There's a sticky at the top of the page that also has some good info that you might want to browse through.
Take it one step at a time and don't overdose on information.
Ask questions, we are here to help you and your daughter. It's a lot to handle all at once!
