<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I hit my head pretty hard and now there is a cut. It hurts a lot and Im feeling dizzy. What could be wrong?  <response>: Based on your symptoms, its possible that you have a head injury. To confirm this, we should perform a radiographic imaging procedure. This could include a head CT scan, an X-ray, or plain x-ray. If your wound is severe, it may require suturing, wound care management, and intravenous fluid replacement as well.
