I'd imagine you're looking for something you can "do" regarding all of this, unfortunately with an injury like this there's no sure fire cure for what's ailing your daughter, but there are things that you could try that can potentially reap profound benefits.

Hearing the brief outline of your daughter's injury, I would recommend taking her to see a craniosacral therapist (the more experience the better). I know a craniosacral therapist who trains people all over the country, if you want to message me with your city or state I can ask him if he knows anyone in your area who's particularly good.
