If you can get the MRI prior to being seen at the neurosurgeons office that will be a huge help, just make sure you get a copy of the imaging via cd so they can review it. Typically a PA will ask you for history, current symptoms, etc. They will do x-rays in office then send you for an MRI. once that is done then typically you go back in for a follow up to review those results and they recommend a treatment plan. My experience is they start with conservative treatments such as physical therapy or steroids or injections, etc. If those things do not work then if they feel surgery is an option they will set you up with an appointment with the actual surgeon to discuss what the surgery would be, you goals and their goals for the procedure and all of the details that go with it. Typically it is not a short process but then again if they get imaging back and seemright away that there is a major issue then surgery may come sooner. That's just my $.02 after having gone through it multiple times.
