This sounds very atypical for herpetic meningitis, at least based on all of the research I've ever done. Everything I've ever read suggests this is one of the forms of benign meningitis and usually doesn't cause severe enough symptoms to be debilitating, nor does it usual cause permanent damage. In worst case scenarios I've heard of people getting on aciclovir, but not all of the stuff you mentioned. Did they do a lumbar puncture and confirm it's in fact meningitis and that HPV is the only possible cause?
How old is your daughter?
Did they type the herpes meningitis as hsv1 or hsv2?
