I've recently been through this same quest trying to get something diagnosed. I found that wait times for an appointment varied WILDLY. Anywhere from 2 or 3 months to 5 days. Obviously I went with the 5 day one. I was also very satisfied with the time I had with the doctor. It was only about 20 minutes but considering what I was there for that was more than sufficient. And I didn't get the feeling I was being rushed through the turnstiles so they could keep cranking out patients.
