Hi My Daughter Had A Horse Accident. She Fratctured Her

Hi my daughter had a horse accident. She fratctured her arm and has a concussion. She started having muscle spasms more like severe convulsions. A couple of times she was hard to wake up. Took her back to the hospital they just sent her home. This worries me bcause this is the same hospital that sent my son home when he was 3 after a horse kick just reconstructed his face and we find out 17 years later he did have brain damage. But he never convulsed like she is. No use taking her back to the hospital they wont do nothing.
