Great to hear of the appt with the neuro on Monday. I suggest you make a list of questions to ask the dr. That way on the way home from the appt you won't be going oh, I wish ai had asked that question. In addition make a list of your current meds and how well they are working, along with a list of meds in the past and how they affected your pain.
Yes, many people do in fact make a pain journal. Its one of those things some drs will look at them and read them, then on the other hand you may get a dr that will not take the time to look at it. Its a mixed bag so to speak. I think they are a very good idea, it gives a good picture of what your day is like.
Nascially it will be like any other ppt with a new dr. You will have a physical exam, checking reflexes and looking in your eyes with a light and such. You will be asked questions about when the pain started and so on.
I really don't much else to tell you other than be honest with the dr about your symptomd and how you are feeling. Good luck on Monday and let us know how it goes. Be sure to have all of your x-ray films and written reports with you at the time of the appt.
