Appointment clarified

Well I spoke with the neurologist’s secretary this morning. I am scheduled for an NCV on the 27th of November but not the EMG. I will be seeing the new Neurologist after the test is done. I then asked her what do I do between now and November if something comes up. Call the old neuro or the new one. She told me to call the old Neuro. She was reviewing my appointment time and said she would also put me on a cancellation list in case an appointment comes up sooner.
