Thinking of this appt. as "getting it over with" won't get you the kind of info you need if this is indeed MS...this is the beginning of your journey with this doctor as your teammate...and you are a teammate also.
You are a consumer purchasing health care...to be informed is to be empowered. I am NEVER afraid or stressed when I see this neuro, because he spends all the time I need answering questions and checking me to see how I'm doing. I feel as if we, with my DH, are a great team in this journey.
I hope that you help your doctor by explaining your symptoms, your concerns, and asking the questions you need answers to. That is why it is so important to go in with them written down-some of us draw a blank, as Dej said, and if you can look at a paper with your questions listed, then you won't have to stress out about not getting them answered.
Good luck! Let us know how it goes...and no matter what, keep checking in here...it's been a Godsend on my journey...these people are the best!
