<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I fell down the stairs last night and hurt my back. Im having trouble moving my legs and I cant feel anything below my waist.  <response>: Im sorry to hear that. Based on your symptoms, Ill need to perform a radiographic imaging procedure to get a better look at your spine. Well start with a plain X-ray, but we may also need to do a scan CT to get a more detailed image. In the meantime, well need to keep you hydrated with intravenous fluid replacement, and well start you on physical therapy exercises as soon as possible. Depending on the severity of your injury, we may also need to involve occupational therapy for speech therapy.
