this is so worrisome. i agree with all the above advice.
a stat call to her neuro, even pcp is in order.
make them call you back.

i also was thinking that a lesion would be causing sx's, however, not all sx's are MS related. her dr needs to work her up for other things as well.
i don't mean to make light of this but maybe she will proposition the dr so he can see for himself her behaviors.

if she's really out of control a trip to the ER may be needed.
