@slw18 I would advise a consult with a spine specialist and a current MRI to determine your status. An X-ray does not show the discs, but it can show if the spaces the discs occupy between vertebrae are abnormal. In general, you can go to a physical therapist, but the PT should be asking you for a report of imaging if there is any question of spinal instability. If you have instability and the vertebrae can slide forward or back, you are at serious risk of injury or paralysis if someone works on your neck. It sounds like your orthopedic doctor does not want to take your case for any further treatment. Surgeons pick and choose cases, and they may avoid difficult cases because a poor surgical outcome can hurt their statistics of success. They are rated by insurance companies and don't want to harm their careers, so they refuse to help patients. They also refuse to help patients who they don't think they can please because they don't want bad reviews posted online. Sometimes they don't help people if they perceive a mental issue also because that patient will never be happy with the outcome. These are things I have heard a surgeon say when presenting cases at a conference for other surgeons and discussing patient selection. Do everything you can to be a good patient that surgeons will want to help.

You do need to find another doctor for another opinion. Spine surgeons like to refer patients to specific neurologists if testing is required, so it makes sense to start with a spine specialist. You do have an old injury, and spine problems from that can sneak up on you. You mentioned "electrical stimulation throughout the body". You might be describing the same symptom I had that was caused by spinal cord compression. When I bent my neck forward, I got an electric shock down my entire body. If that is what you have, You should see a spine surgeon ASAP. Choose your spine surgeon carefully. Some are gifted; some are not, so do your research and find the best you can. Check your insurance coverage and make sure they are in network. Spine surgery is very expensive. If you do make another appeal to get into Mayo, do that with current imaging of your spine issues directed to a spine surgeon or to the neurosurgery department. Your primary care doctor could order MRI imaging based on your symptoms for a referral to a spine specialist. There are orthopedic and neurosurgery spine experts and either can operate on the spine. I chose my spine surgeon because his areas of interest matched my case, and because when I read his papers, I knew he would understand my symptoms because it referenced leg pain caused by cervical stenosis (cord compression in the neck). Here is my patient story. Let me know if I can be of further assistance. I was turned down 5 times before I came to Mayo.
