@fitnhealthy I think that @colleenyoung is referring to a different situation that we (my husband and I) were faced with. In our case my husband felt that the provider he was seeing in Urology wasn't responsive to his needs and ordered lab tests that did not help (and actually deterred) from the decision making. What my husband was advised to do was to contact the Nurse Manager in Urology and ask for a different provider - in this case an MD who specializes in prostate. I was present at Mayo Clinic when my husband talked with the Nurse Manager and she listened, was responsive and did help my husband to make an appointment with a new provider.

I'm not sure if what I wrote helps unless you think that contacting the Nurse Manager - the person who manages the practice in Neurology - would be helpful for you in order to get your appointment moved up in time.
