"Ultra Sound Scan"

Doctor faxed referral on four separate occasions, marked urgent on 19th November but still awaiting an appointment. Been in severe pain for over three weeks and unable to treat cause until results of scan received. I have tried to chase the appointment by calling the department and even went to the hospital to try to sort it out. I was informed they would need to speak to my doctor to clarify the urgency and would call me back to confirm an appointment but I've heard nothing!
