I just got back from the Mayo Clinic in Rochester. All we had to do to schedule an appointment was call. We called in Later August/September I believe? And my appointment was about 2 weeks ago. So, all you should have to do is call and explain your problem, and they'll work you in. Also, it says that you can just show up at the Clinic and they'll work you in within a few days. I would reccomend the trip. After lots of wrong diagnoses here in Atlanta, we finally got an accurate one at Mayo. They are so thourough-- it was overall a very good experince and I would reccomend going to anyone who hasn't gotten the answers they need medically. If you have the time and the means to go to Mayo and just wait for a cancellation (and their are a lot of cancellations) I would go for it. I can't imagine them not being helpful. If you don't want to do that, Call the Mayo Clinics in Arizona & Florida to see if they can get you in any sooner. Good luck!!
