Hello @wascaly, first off I'd like to share with you that I too was turned down from being seen at Mayo and felt quite rejected. I really didn't understand at the time but was able to look back and realize that there was no more medical intervention to help me other than my own self intervention of acceptance of my condition and challenge myself to figure out how I was going to learn to best live with my circumstances. That is where Mayo Clinic's pain rehab center came in. Here is an overview of the program:

If Cleveland Clinic can't offer any more medical intervention, or you decide enough is enough regarding medications, procedures, treatments, I suggest considering Mayo Clinic's Pain Rehab Center. The PRC helps folks wean off of medications that are not medically necessary, they help folks get back to a more physically fit moderated lifestyle within their abilities, educate through cognitive behavioral therapy which supports emotional and behavioral changes, occupational therapy, nutrition....the list goes on.

I see that you are moving to Florida in 6 months, that's awesome! What I would give to live in a warm climate year round. Jacksonville has a PRC which would be the closest to you. Will you please let me know what your thoughts are regarding the program and whether it might be of interest to you?
