Hi. I had sent my records to Mayo too who felt they couldn't help me at this time. So I went to Cleveland Clinic pain clinic and anestesology. I have mixed feelings on Cleveland but if you want to ask any ?'s I would be happy to answer. I'm thinking of resending my records to Mayo again. I have heard good things about John Hopkins though not for this issue but care in general. A very pro active approach but this I don't know for sure. Good luck.
