How lucky for you, Joanne to get moved up so quickly on the waiting list after only 3 months! I know you’re anxious to get this visit under way.

Do you have your patient portal set up with Mayo? https://onlineservices.mayoclinic.org/content/staticpatient/showpage/patientonline
That basically becomes your lifeline with the clinic for all your appointments, your health records and for contacting the people who are on your health team should you have any questions and concerns.

When you go in for your initial appointment with the specialist, the doctor will meet with you to find out what further tests may be needed. Especially in your situation where you have so many different symptoms, there may be a need for several departments to collaborate to get you a complete diagnosis. So, for your first visit it would be impractical to arrange those appointments without meeting with you to see what is required. Does that make sense?
Often, if there is anything more they need, appointments can be set up within minutes or hours within the same day or the next.

My suggestion would be to plan on staying in Jacksonville at least 2-3 days in case you have added appointments. Most hotels have a 24 hour cancellation notice so that would give you time to cancel the extra day if not needed.
Have you booked your hotel yet?
