Your daughter is 8 yrs.old, and she should fall under your State's Medical Program for Children.
Contact the Department of Human Svc. office in your area, and request a medical application for your child. All children under the age of 18 should be able to be covered. Depending upon your income, you may not have to pay anything, or at the most, a small fee to cover your child's medical expenses..
Before RSD/CRPS, I was a social worker for the State of Ok.
I hope this assists you and your child.
