my kid was in a very bad headon collision shes still dizzy & headaches should i take her back to the doc?

The simple answer is Yes. N S is correct. Head and neck injuries are nothing to ignore. Even though it sounds as if you've already taken your child to a physician, there may need to be some further testing.

The article below describes in some detail some of the symptoms of various forms of head injuries. Hope this helps.

Yes I would take you child back as a matter of urgency, could have sustained frontal lobe damage, which in turn could cause epilepsy. The accident must have been very recent. Was she not kept in hospital for observations? Did she suffer these symptoms prior to the accident? If the latter is no, well obviously, something is very wrong.

Good luck!

Yes she probably has a concussion and needs treatment.

I would actually take her to the ER

yes of course.
