I'm writing a Harry Potter-verse fanfiction taking place in winter/spring of 2025/2026, in Liverpool, England. My main character, a 31-year-old female (married with one child) hits her head and gets amnesia. What would be hospital protocol in this situation? If you're not acquainted with the Harry Potter universe, feel free to give me real world answers. Anything is helpful. How long would she be in the hospital? What would doctors' orders be? Assume her head injury is relatively mild, but enough to cause amnesia. Perhaps a mild concussion in just the right spot.
