Hello Liz -
Here is the information about the Mayo Clinic Pain RehabilitationCenter:
https://www.mayoclinic.org/departments-centers/pain-rehabilitation-center/sections/overview/ovc-20481691
If you prefer to self-refer, here is the link for requesting an assessment at any Mayo Clinics.

After you fill in the identifying information, you get to the page where you tell them what you need & where you can travel.

Good luck as you look for a solution. Even if Mayo cannot accommodate you, there are other programs available. It will take some work to find a suitable one near you.
