sadly i can't answer your question. you'll have to keep in close contact with her medical providers for that. but i did want to extend my thoughts to and your family (and especially your sister! ) at this difficult time. i wish you all the best and hope for a positive outcome.
my sister is in her 30's she can't open her mouth sallow in lots of pain and can't talk or walk. all this started after she had a tooth pulled. what could be wrong with her? she is in the hospital now and they have said her body is shutting down.
