@nursecurt, I'm so sorry that you are in such pain. It is such a gut punch to be denied an appointment. It sounds like you have taken the right steps to get an appointment at Mayo Clinic. Mayo Clinic has more requests for appointments than available openings. You may wish to ask your treating doctor to submit a referral on your behalf. You'll find additional tips shared by mmbers in this discussion:

Another possibility for you may be to request an appointment with an institution that is part of the Mayo Clinic Care Network.

The Mayo Clinic Care Network is a select group of independent health systems that are granted special access to Mayo Clinic's extensive knowledge and world-leading medical expertise. The Mayo Clinic Care Network helps keep care local by providing guidance and answers to many questions that might otherwise require a referral to a specialist. See the member hospitals here:
