Hi Footprints,
WELCOME TO THE NEUROTALK FORUM COMMUNITY!
I don't understand why her neuro is holding off on making a decision with all of the clinical and physical symptoms your sister is exhibiting. Especially since these are becoming more chronic than acute in nature. Maybe she needs to get a second opinion at an MS Clinic in your area. Most neuro's welcome a second opinion especially from an MS specialist.
I hope all improves with your sister and that she gets to the bottom of her problems soon.
BTW, I agree with the information that Snoopy has posted. She's right on the spot.
