After a year and a half of testing, including two Spinal Angiographs, my Mayo neurologists cannot pinpoint the origins of my thoracic myelopathy. He would be agreeable for me seeking a second opinion. I live in northern Wisconsin, and have been to the Marshfield Clinic and UW-Madison neurology departments for diagnosis/treatment. Both institutions referred me to the Mayo Clinic, neurology department, as they are recognized as one of the nation’s top neurology departments. Where does one go to seek a second opinion if the Mayo Clinic does not have an answer (“the place to go to find answers”)?
