It was suggested by another doctor in my primary care office that I go to John Hopkins but I chose Mayo Clinic. My own doctor was against going anywhere saying they would not discover anything new. He was right. The doctor that suggested John Hopkins reasoned because John Hopkins tried new things was the right attitude I believe. Mayo Clinic was good that they search other things in my health problems but they really pushed for you comming back to see their pain management doctors. I just couldn't do that.
