@shellyg Urgent cry for help.
First if his pain is uncontrolled, please seek advice from your local emergency room first!!

Second, here is a link for Mayo Clinic Pain Rehabilitation Clinic. http://www.mayoclinic.org/departments-centers/pain-rehabilitation-center/overview

Third, very simple process at getting seen at Mayo Clinic, you may call and request an appointment. The scheduling specialist will direct you to the most appropriate department and set you up. If you prefer you may schedule the appointment online. Here is the link for scheduling.
